Introduction

If you've ever hit Redis memory limits, struggled with slow cache operations, or watched your cache storage balloon to gigabytes, you're not alone. Caching large datasets in Laravel applications presents unique challenges that standard caching solutions don't adequately address.

Laravel SmartCache, created by Ismael Azaran, revolutionizes how your application handles large-scale caching. This intelligent package automatically optimizes cache operations through compression (achieving up to 70% size reduction), smart chunking, and adaptive strategies—all while maintaining Laravel's familiar API.

In this comprehensive guide, you'll learn how to implement SmartCache to handle everything from 10,000+ product catalogs to massive API responses, without writing a single line of optimization code. Whether you're building an e-commerce platform, SaaS application, or data-intensive dashboard, SmartCache provides production-ready solutions that scale.

Why Laravel's Default Cache Falls Short

Before exploring SmartCache's capabilities, let's understand the fundamental limitations of Laravel's standard caching when handling large datasets.

The Size Problem

Laravel's Cache facade stores data as-is through serialization. For small datasets, this works perfectly. For large datasets, it creates serious problems:

use Illuminate\Support\Facades\Cache;
 
// Caching 15,000 products with relationships
$products = Product::with(['category', 'images', 'variants', 'reviews'])
    ->active()
    ->get();
 
Cache::put('product_catalog', $products, 3600);
// Storage required: ~4.2 MB serialized data
// Redis memory impact: Immediate 4.2 MB consumption
// Network transfer: 4.2 MB per retrieval

This straightforward approach causes:

  • Excessive memory usage: Your cache server's RAM fills quickly
  • Network bottlenecks: Transferring large payloads takes time
  • Driver limitations: Redis typically limits single keys to 512MB
  • Slow serialization: Converting huge objects is CPU-intensive

The Stampede Problem

When cached data expires under heavy traffic, disaster strikes. Multiple concurrent requests simultaneously regenerate the same expensive query:

// Under high load, this scenario is catastrophic
$analytics = Cache::remember('daily_analytics', 3600, function () {
    // Complex query taking 5+ seconds
    return Order::with(['customer', 'items', 'payments'])
        ->whereBetween('created_at', [now()->subDay(), now()])
        ->get();
});
 
// What actually happens when cache expires:
// - Request 1 starts expensive query
// - Request 2-100 start identical queries
// - Database gets hammered with 100 simultaneous queries
// - Response times skyrocket
// - Users experience timeouts

The Complexity Problem

Real-world applications cache deeply nested structures—dashboards with multiple data sources, API aggregations, computed analytics:

$dashboard = [
    'sales' => Order::todayStats(),           // 500 records
    'customers' => Customer::activeToday(),   // 1,200 records
    'products' => Product::topSelling(),      // 300 records
    'analytics' => Analytics::compute(),       // Complex calculations
    'charts' => ChartData::generate(),         // Array of plot points
];
 
Cache::put('admin_dashboard', $dashboard, 600);
// Result: 3.5 MB of nested, complex data
// Serialization time: 180ms
// Retrieval time: 145ms
// Memory consumption: Significant

These challenges compound as your application scales. SmartCache addresses each of these problems systematically and automatically.

SmartCache: The Intelligent Solution

SmartCache isn't just another caching package—it's an intelligent optimization layer that sits between your application and Laravel's cache system, making smart decisions about how to store and retrieve data.

The Core Philosophy

SmartCache operates on three fundamental principles that set it apart:

1. Zero Configuration, Immediate Benefit

Unlike other optimization tools requiring extensive setup, SmartCache works out of the box:

use SmartCache\Facades\SmartCache;
 
// That's it - optimization happens automatically
SmartCache::put('large_dataset', $data, 3600);

No configuration files to edit, no complex setup procedures, no optimization decisions to make. Install it, use it, benefit immediately.

2. Transparent Optimization

Your code remains clean and Laravel-like while SmartCache works behind the scenes:

// Your code stays simple
$users = SmartCache::remember('active_users', 3600, function () {
    return User::with('profile', 'subscriptions')->active()->get();
});
 
// SmartCache automatically:
// - Analyzes data size and structure
// - Applies gzip compression if beneficial
// - Chunks large arrays intelligently
// - Optimizes for your cache driver
// - Stores with metadata for reconstruction
// - Returns exactly what you cached, perfectly reassembled

3. API Compatibility

Every method you know from Laravel's Cache works identically in SmartCache:

// All these work exactly as you expect
SmartCache::put($key, $value, $ttl);
SmartCache::get($key, $default);
SmartCache::remember($key, $ttl, $callback);
SmartCache::forget($key);
SmartCache::has($key);
SmartCache::increment($key);
SmartCache::tags(['tag'])->put($key, $value, $ttl);

This compatibility means zero learning curve and instant productivity.

How SmartCache Makes Decisions

When you cache data, SmartCache analyzes it through an intelligent decision tree:

// Step 1: Serialize and measure
$serialized = serialize($yourData);
$size = strlen($serialized);
 
// Step 2: Should we compress?
if ($size >= 50KB) {  // Configurable threshold
    // Apply gzip compression
    // Typical result: 60-80% size reduction
    $compressed = gzcompress($serialized, 6);  // Level 6 = balanced
    $metadata['compressed'] = true;
}
 
// Step 3: Should we chunk?
if (is_array($yourData) && $size >= 100KB) {  // Configurable threshold
    // Split into 1000-item chunks (configurable)
    $chunks = array_chunk($yourData, 1000);
    // Store each chunk separately
    // Store chunk metadata for reassembly
    $metadata['chunked'] = true;
}
 
// Step 4: Apply driver-specific optimizations
// Redis: Binary-safe operations, pipelining
// File: Atomic writes, directory optimization
// Database: BLOB handling, compression awareness

This intelligent analysis happens instantly and automatically, requiring no intervention from you.

The SmartCache Advantage

Here's what makes SmartCache exceptional:

Dramatic Size Reduction: Up to 70% smaller cache footprint through intelligent compression Faster Operations: Smaller payloads mean faster network transfers and quicker serialization No Size Limits: Chunking eliminates single-key size restrictions Stampede Prevention: Built-in distributed locks protect against concurrent regeneration Memory Efficiency: Lazy loading keeps memory usage constant regardless of data size Production Ready: Used in high-traffic applications serving millions of requests

Getting Started with SmartCache

Setting up SmartCache takes less than five minutes and requires no configuration to start benefiting from its intelligent optimizations.

System Requirements

Before installing, verify your environment meets these requirements:

  • PHP 7.4 or higher (PHP 8.0+ recommended for best performance)
  • Laravel 8.0 or higher (tested through Laravel 10.x)
  • Cache Driver: Any Laravel-supported driver (Redis, File, Database, Memcached)

SmartCache works with all Laravel cache drivers, though Redis is recommended for production environments due to its speed and feature support.

Installation Process

Install SmartCache via Composer in your Laravel project:

composer require iazaran/smart-cache

The package uses Laravel's auto-discovery feature, so the service provider registers automatically. You're ready to use SmartCache immediately after installation.

Optional: Publish Configuration

While SmartCache works perfectly with defaults, publishing the configuration file gives you fine-grained control:

php artisan vendor:publish --tag=smart-cache-config

This creates config/smart-cache.php where you can customize thresholds, compression levels, and optimization strategies.

Verification Test

Confirm SmartCache is working correctly with a simple test:

// routes/web.php or tinker
use SmartCache\Facades\SmartCache;
 
// Store test data
$testData = range(1, 5000);
SmartCache::put('test_smartcache', $testData, 60);
 
// Retrieve and verify
$retrieved = SmartCache::get('test_smartcache');
 
if ($testData === $retrieved) {
    echo "SmartCache is working perfectly!";
} else {
    echo "Something went wrong - check your cache configuration";
}

If the verification passes, you're ready to start optimizing your cache operations.

First Implementation

Let's replace your first Cache call with SmartCache:

// Before: Standard Laravel Cache
use Illuminate\Support\Facades\Cache;
 
$products = Cache::remember('products', 3600, function () {
    return Product::with('category')->get();
});
 
// After: SmartCache (just change the import)
use SmartCache\Facades\SmartCache;
 
$products = SmartCache::remember('products', 3600, function () {
    return Product::with('category')->get();
});

That's it! Your products are now automatically optimized with compression and chunking when beneficial.

Environment Configuration

For different environments, configure SmartCache through environment variables:

# .env file
CACHE_DRIVER=redis
SMART_CACHE_COMPRESSION_ENABLED=true
SMART_CACHE_COMPRESSION_LEVEL=6
SMART_CACHE_CHUNK_SIZE=1000

Gradual Migration Strategy

Don't migrate everything at once. Start strategically:

Week 1: Replace caching for your largest dataset Week 2: Migrate API response caching Week 3: Convert dashboard and analytics caching Week 4: Replace remaining Cache calls with SmartCache

This gradual approach lets you monitor impact and adjust configurations based on real performance data.

Core Features Explained

SmartCache provides six core features that work together to optimize your cache operations. Understanding each feature helps you leverage SmartCache's full potential.

1. Automatic Gzip Compression

SmartCache applies industry-standard gzip compression to large payloads, achieving impressive size reductions:

// Large API response
$apiData = Http::get('https://api.example.com/large-dataset')->json();
 
SmartCache::put('api_response', $apiData, 3600);
 
// What SmartCache does:
// - Serializes the data
// - Measures size: 850 KB
// - Threshold check: 850 KB > 50 KB ✓
// - Applies gzip compression (level 6)
// - Final size: 280 KB (67% reduction)
// - Stores compressed data with metadata
 
// Retrieval is seamless
$data = SmartCache::get('api_response');
// SmartCache automatically decompresses
// Returns original 850 KB of data
// You never see the compression/decompression

Compression Benefits:

  • 60-80% typical size reduction for text-heavy data
  • Faster network transfer from cache server
  • Lower memory consumption on cache server
  • Extended capacity before hitting storage limits

When Compression Activates:

  • Data size exceeds 50 KB (default, configurable)
  • Driver supports binary data (all major drivers do)
  • Compression is enabled in configuration (enabled by default)

2. Intelligent Array Chunking

For large arrays and collections, SmartCache automatically splits data into manageable chunks:

// Caching 25,000 user records
$users = User::with('profile', 'preferences')->get();
 
SmartCache::put('all_users', $users, 3600);
 
// SmartCache's chunking process:
// 1. Detects array/collection with 25,000 items
// 2. Calculates size: 3.2 MB
// 3. Threshold check: 3.2 MB > 100 KB ✓
// 4. Chunks into 25 groups of 1,000 items each
// 5. Stores chunks as: all_users:chunk:0, all_users:chunk:1, ..., all_users:chunk:24
// 6. Stores metadata: all_users:meta (chunk count, original structure info)
 
// Retrieval assembles chunks automatically
$users = SmartCache::get('all_users');
// Returns complete 25,000-item collection
// Chunks fetched and reassembled transparently

Chunking Benefits:

  • Bypasses single-key size limits in Redis and other drivers
  • Enables parallel chunk retrieval for faster performance
  • Supports lazy loading for memory efficiency
  • Makes large datasets manageable

3. Driver-Aware Optimization

SmartCache adapts its behavior based on your cache driver's capabilities:

// Redis Driver: SmartCache uses
// - Binary-safe storage operations
// - Pipeline commands for multi-chunk operations
// - Tag support for group invalidation
// - Atomic operations where beneficial
 
// File Driver: SmartCache uses
// - Atomic file writes for data safety
// - Optimized directory structures
// - Filesystem-appropriate compression levels
// - Careful path management
 
// Database Driver: SmartCache uses
// - BLOB column optimization
// - Query optimization for chunk retrieval
// - Transaction safety for multi-chunk writes
// - Index-aware key generation

This driver awareness ensures optimal performance regardless of your infrastructure choices.

4. Lazy Loading for Memory Efficiency

Enable lazy loading to process large cached collections without loading everything into memory:

// Enable in config
config(['smart-cache.strategies.chunking.lazy_loading' => true]);
 
// Cache 100,000 records
$records = Record::all();
SmartCache::put('all_records', $records, 3600);
 
// Retrieve with lazy loading
$records = SmartCache::get('all_records');
 
// Memory usage stays constant while iterating
foreach ($records as $record) {
    processRecord($record);
    // Each chunk loads on-demand
    // Previous chunks released from memory
    // Peak memory: ~15 MB instead of 450 MB
}

Lazy Loading Benefits:

  • 30-50% reduction in memory usage
  • Constant memory consumption regardless of collection size
  • Enables processing of datasets larger than available RAM
  • Transparent to your application code

5. Memory Memoization

Access cached data instantly within the same request without repeatedly hitting the cache store:

$memo = SmartCache::memo();
 
// First access: Hits cache store (Redis/File/etc)
$categories = $memo->remember('categories', 3600, function () {
    return Category::with('products')->get();
});  // Takes 8ms
 
// Subsequent accesses in same request: Memory only
$categories = $memo->get('categories');  // Takes 0.01ms
$categories = $memo->get('categories');  // Takes 0.01ms
 
// Perfect for loops
foreach ($orders as $order) {
    // Each unique customer cached once, then instant access
    $customer = $memo->remember("customer_{$order->customer_id}", 3600, function () use ($order) {
        return Customer::find($order->customer_id);
    });
}

Memoization Benefits:

  • 10-100x faster than repeated cache store access
  • Zero network overhead for repeated queries
  • Significant performance gain in loop operations
  • Automatic cleanup after request completes

6. Distributed Locks

Prevent cache stampedes with built-in distributed locking:

$lock = SmartCache::lock('expensive_report', 30);
 
if ($lock->get()) {
    try {
        // Only ONE process executes this
        $report = Report::generateExpensiveReport();
        SmartCache::put('monthly_report', $report, 3600);
    } finally {
        $lock->release();
    }
} else {
    // Other processes wait and retrieve cached result
    sleep(1);
    $report = SmartCache::get('monthly_report');
}
 
// Or use callback pattern (cleaner)
$report = SmartCache::lock('expensive_report', 30)->get(function () {
    $data = Report::generateExpensiveReport();
    SmartCache::put('monthly_report', $data, 3600);
    return $data;
});

These six features work together seamlessly, providing comprehensive optimization without requiring complex configuration or code changes.

Automatic Compression in Action

Let's dive deep into how SmartCache's compression feature works and how to optimize it for your specific use cases.

Compression Decision Process

SmartCache evaluates every cache operation through a compression decision tree:

// Your simple code
SmartCache::put('reports', $reportData, 3600);
 
// SmartCache's internal compression logic
function shouldCompress($data, $config) {
    $serialized = serialize($data);
    $size = strlen($serialized);
    $threshold = $config['thresholds']['compression']; // Default: 50KB
    
    if (!$config['strategies']['compression']['enabled']) {
        return false; // Compression disabled
    }
    
    if ($size < $threshold) {
        return false; // Data too small, compression overhead not worth it
    }
    
    // Check if data type benefits from compression
    if (is_highly_compressible($data)) {
        return true;
    }
    
    return true; // Default: compress if above threshold
}

Compression Levels Explained

SmartCache supports compression levels 1-9, each with different tradeoffs:

// config/smart-cache.php
'strategies' => [
    'compression' => [
        'level' => 6, // Default balanced level
    ],
],

Level 1-3 (Fast Compression):

config(['smart-cache.strategies.compression.level' => 3]);
 
// Characteristics:
// - Compression ratio: 40-50%
// - Speed: Very fast (minimal CPU usage)
// - Best for: Frequently written data, real-time applications
// - Example savings: 1 MB → 500-600 KB
 
SmartCache::put('realtime_metrics', $metrics, 60);

Level 4-6 (Balanced - Recommended):

config(['smart-cache.strategies.compression.level' => 6]);
 
// Characteristics:
// - Compression ratio: 60-70%
// - Speed: Good balance
// - Best for: Most applications (default)
// - Example savings: 1 MB → 300-400 KB
 
SmartCache::put('product_catalog', $products, 3600);

Level 7-9 (Maximum Compression):

config(['smart-cache.strategies.compression.level' => 9]);
 
// Characteristics:
// - Compression ratio: 70-80%
// - Speed: Slower (higher CPU usage)
// - Best for: Infrequently written, frequently read data
// - Example savings: 1 MB → 200-300 KB
 
SmartCache::put('static_content', $content, 86400);

Adaptive Compression Mode

SmartCache can automatically adjust compression levels based on data characteristics:

// Enable adaptive mode
config(['smart-cache.strategies.compression.mode' => 'adaptive']);
 
// SmartCache automatically chooses compression level
SmartCache::put('hot_data', $frequentData, 300);
// Adaptive decision: Level 3 (fast, data changes frequently)
 
SmartCache::put('cold_data', $archiveData, 86400);
// Adaptive decision: Level 8 (maximize compression, rarely changes)

Adaptive Mode Logic:

  • Analyzes data update frequency
  • Considers TTL (short TTL = lower compression)
  • Evaluates data compressibility
  • Balances CPU cost vs storage savings

Real-World Compression Examples

Example 1: E-Commerce Product Catalog

// 5,000 products with images, descriptions, metadata
$products = Product::with(['images', 'category', 'variants', 'attributes'])->get();
 
// Standard Laravel Cache
Cache::put('products', $products, 3600);
// Size stored: 3.8 MB
// Memory consumption: 3.8 MB
// Retrieval time: 145ms
 
// SmartCache with Compression
SmartCache::put('products', $products, 3600);
// Size stored: 1.1 MB (71% reduction)
// Memory consumption: 1.1 MB (71% reduction)
// Retrieval time: 98ms (33% faster due to smaller payload)

Example 2: API Response Caching

// Large JSON API response
$apiResponse = Http::get('https://api.external.com/dataset')->json();
 
// Without SmartCache
Cache::put('api_data', $apiResponse, 1800);
// Original size: 2.4 MB
// Network transfer: 2.4 MB per request
 
// With SmartCache
SmartCache::put('api_data', $apiResponse, 1800);
// Compressed size: 680 KB (72% reduction)
// Network transfer: 680 KB per request
// 3.5x faster retrieval over network

Example 3: Analytics Dashboard Data

$analytics = [
    'sales' => SalesReport::generate(),        // 850 KB
    'customers' => CustomerAnalytics::get(),   // 620 KB
    'products' => ProductStats::compute(),     // 450 KB
    'trends' => TrendAnalysis::calculate(),    // 380 KB
];
 
// Total size: 2.3 MB
 
SmartCache::put('dashboard_data', $analytics, 600);
// Compressed: 720 KB (69% reduction)
// Dashboard loads 3.2x faster

Compression Performance Metrics

Based on production data across various application types:

| Data Type | Typical Compression Ratio | Speed Impact | Best Level | |-----------|--------------------------|--------------|------------| | JSON/API Responses | 65-75% | +15ms write, -8ms read | 6-7 | | HTML Content | 70-80% | +12ms write, -12ms read | 7-8 | | Database Collections | 60-70% | +20ms write, -10ms read | 5-6 | | Mixed Arrays | 55-65% | +18ms write, -7ms read | 6 | | Binary Data | 15-25% | +25ms write, +5ms read | 3 (not recommended) |

Tuning Compression for Your Application

Step 1: Measure Current State

Route::get('/test-compression', function () {
    $data = YourModel::getTypicalDataset();
    
    // Test without compression
    $start = microtime(true);
    Cache::put('test_no_compress', $data, 60);
    $writeTimeNoCompress = (microtime(true) - $start) * 1000;
    
    $start = microtime(true);
    $retrieved = Cache::get('test_no_compress');
    $readTimeNoCompress = (microtime(true) - $start) * 1000;
    
    $sizeNoCompress = strlen(serialize($data));
    
    // Test with SmartCache
    $start = microtime(true);
    SmartCache::put('test_compress', $data, 60);
    $writeTimeCompress = (microtime(true) - $start) * 1000;
    
    $start = microtime(true);
    $retrieved = SmartCache::get('test_compress');
    $readTimeCompress = (microtime(true) - $start) * 1000;
    
    // Get compressed size (implementation-specific)
    $sizeCompress = Cache::get('test_compress:meta')['compressed_size'] ?? 0;
    
    return [
        'original_size' => round($sizeNoCompress / 1024) . ' KB',
        'compressed_size' => round($sizeCompress / 1024) . ' KB',
        'reduction' => round((1 - $sizeCompress / $sizeNoCompress) * 100) . '%',
        'write_time_increase' => round($writeTimeCompress - $writeTimeNoCompress, 2) . 'ms',
        'read_time_decrease' => round($readTimeNoCompress - $readTimeCompress, 2) . 'ms',
    ];
});

Step 2: Adjust Based on Results

// If write performance is critical
config(['smart-cache.strategies.compression.level' => 3]);
 
// If storage savings are critical
config(['smart-cache.strategies.compression.level' => 8]);
 
// If balance is needed (most cases)
config(['smart-cache.strategies.compression.level' => 6]); // Default

Compression is SmartCache's most impactful feature for most applications. Understanding how it works helps you leverage it effectively for your specific use case.

Smart Chunking Strategy

While compression reduces data size, chunking solves a different problem: managing data that's too large to handle as a single unit. SmartCache's intelligent chunking makes working with massive datasets effortless.

Why Chunking Matters

Traditional caching hits hard limits with large arrays:

// Problem: Caching 50,000 records
$users = User::with('profile', 'orders', 'preferences')->get();
 
// Standard Laravel Cache issues:
Cache::put('all_users', $users, 3600);
 
// ❌ Redis: "ERR string exceeds maximum allowed size"
// ❌ Memory: 380 MB peak usage during serialization
// ❌ Network: 340 MB transferred on each retrieval
// ❌ Time: 2.5 seconds to serialize/deserialize

SmartCache's chunking eliminates these problems completely:

// Solution: SmartCache chunks automatically
SmartCache::put('all_users', $users, 3600);
 
// ✅ Redis: No size limit errors (data split across keys)
// ✅ Memory: 45 MB peak usage (chunks processed individually)
// ✅ Network: Optimized transfer (parallel chunk retrieval)
// ✅ Time: 680ms to process (much faster)

How Chunking Works

SmartCache's chunking process is sophisticated yet transparent:

// Step 1: Size Analysis
$data = Product::with('variants', 'images')->get(); // 18,000 products
$serialized = serialize($data);
$size = strlen($serialized); // 5.2 MB
 
// Step 2: Chunking Decision
$threshold = config('smart-cache.thresholds.chunking'); // Default: 100 KB
 
if ($size > $threshold && is_array($data)) {
    // Proceed with chunking
    $chunkSize = config('smart-cache.strategies.chunking.chunk_size'); // Default: 1000
    
    // Step 3: Split Data
    $chunks = array_chunk($data, $chunkSize);
    // Result: 18 chunks of 1000 items each
    
    // Step 4: Store Chunks
    foreach ($chunks as $index => $chunk) {
        Cache::put("products:chunk:{$index}", $chunk, 3600);
    }
    
    // Step 5: Store Metadata
    Cache::put("products:meta", [
        'chunked' => true,
        'chunk_count' => 18,
        'chunk_size' => 1000,
        'original_count' => 18000,
        'created_at' => now(),
    ], 3600);
}
 
// Step 6: Retrieval (transparent to you)
$products = SmartCache::get('products');
// SmartCache reads metadata
// Fetches all 18 chunks
// Reassembles into original collection
// Returns complete 18,000-item collection

Chunk Size Optimization

Choosing the right chunk size impacts performance:

Small Chunks (100-500 items):

config(['smart-cache.strategies.chunking.chunk_size' => 500]);
 
// Pros:
// - Lower memory usage per chunk
// - Faster individual chunk operations
// - Better for very large datasets (100K+ items)
 
// Cons:
// - More cache keys to manage
// - Slightly more overhead
// - More network round-trips
 
// Best for: Datasets with 100,000+ items

Medium Chunks (500-1,500 items - Recommended):

config(['smart-cache.strategies.chunking.chunk_size' => 1000]);
 
// Pros:
// - Balanced performance
// - Reasonable memory usage
// - Optimal for most use cases
 
// Cons:
// - None significant
 
// Best for: Most applications (10K-100K items)

Large Chunks (1,500-5,000 items):

config(['smart-cache.strategies.chunking.chunk_size' => 3000]);
 
// Pros:
// - Fewer cache keys
// - Less overhead
// - Fewer network operations
 
// Cons:
// - Higher memory per chunk
// - Slower individual operations
// - May approach size limits
 
// Best for: Smaller datasets (5K-20K items) where chunking barely needed

Smart Sizing: Automatic Chunk Size Calculation

Enable SmartCache to calculate optimal chunk size automatically:

config(['smart-cache.strategies.chunking.smart_sizing' => true]);
 
// SmartCache analyzes your data and determines best chunk size
SmartCache::put('dynamic_data', $data, 3600);
 
// Decision factors:
// - Total item count
// - Average item size
// - Available memory
// - Cache driver capabilities
// - Network latency considerations

Lazy Loading: Memory-Efficient Processing

For truly massive datasets, enable lazy loading to load chunks on-demand:

// Enable lazy loading
config(['smart-cache.strategies.chunking.lazy_loading' => true]);
 
// Cache 100,000 records
$records = Record::all();
SmartCache::put('all_records', $records, 3600);
 
// Retrieve with lazy loading
$records = SmartCache::get('all_records');
// Type: LazyChunkedCollection
// Memory loaded: Only metadata (~2 KB)
 
// Process efficiently
foreach ($records as $record) {
    processRecord($record);
    // Chunk 1 loads: 1000 records (~1.2 MB)
    // Process chunk 1 items...
    // Chunk 1 released from memory
    // Chunk 2 loads: 1000 records (~1.2 MB)
    // Process chunk 2 items...
    // Pattern continues...
}
 
// Result:
// - Peak memory: ~1.5 MB (constant)
// - Without lazy loading: ~125 MB (all at once)
// - Memory savings: 98.8%

Chunking with Compression

SmartCache combines chunking and compression for maximum efficiency:

// Large dataset that benefits from both
$products = Product::with('everything')->get(); // 30,000 products
 
SmartCache::put('full_catalog', $products, 3600);
 
// SmartCache process:
// 1. Analyzes size: 8.5 MB total
// 2. Chunking: Splits into 30 chunks of 1000 items
// 3. Compression: Compresses each chunk individually
//    - Chunk size before compression: ~283 KB
//    - Chunk size after compression: ~95 KB (66% reduction)
// 4. Storage: 30 keys at ~95 KB each = 2.85 MB total
// 
// Final result: 8.5 MB → 2.85 MB (66% reduction)
// Plus: No single-key size limit issues
// Plus: Parallel chunk retrieval possible

Parallel Chunk Retrieval

With Redis and proper configuration, SmartCache can retrieve chunks in parallel:

// SmartCache automatically uses parallel retrieval when beneficial
$data = SmartCache::get('large_chunked_dataset');
 
// Behind the scenes (with Redis):
// 1. Read metadata
// 2. Identify 25 chunks needed
// 3. Use Redis pipeline to fetch multiple chunks simultaneously
// 4. Reassemble in correct order
// 
// Performance gain:
// - Sequential: 25 chunks × 4ms = 100ms
// - Parallel: ~15ms total
// - 6.7x faster retrieval

Real-World Chunking Scenario

E-Commerce Product Export:

class ProductExportService
{
    public function generateExport()
    {
        // 45,000 products with full details
        $products = Product::with([
            'category',
            'brand',
            'images',
            'variants.stock',
            'reviews' => fn($q) => $q->approved(),
        ])->get();
        
        // Cache for multiple export format generations
        SmartCache::put('product_export_data', $products, 1800);
        
        // SmartCache automatically:
        // - Chunks into 45 groups of 1000
        // - Compresses each chunk (~250 KB → ~80 KB)
        // - Total storage: 3.6 MB instead of 11.2 MB
        
        return $products;
    }
    
    public function exportToCsv()
    {
        // Retrieve with lazy loading for memory efficiency
        config(['smart-cache.strategies.chunking.lazy_loading' => true]);
        
        $products = SmartCache::get('product_export_data');
        
        $csv = fopen('php://temp', 'r+');
        
        // Process one chunk at a time
        foreach ($products as $product) {
            fputcsv($csv, $product->toArray());
            // Memory stays constant at ~2 MB
        }
        
        rewind($csv);
        return stream_get_contents($csv);
    }
}

Chunking Configuration Strategy

For Your Application:

// Determine your typical dataset sizes
$averageCollectionSize = 15000; // items
$averageItemSize = 2; // KB
 
// Calculate total size
$totalSize = $averageCollectionSize * $averageItemSize; // 30 MB
 
// Set chunk size to keep chunks around 100-200 KB
$targetChunkSize = 150; // KB
$itemsPerChunk = $targetChunkSize / $averageItemSize; // 75 items
 
// Configure
config([
    'smart-cache.thresholds.chunking' => 1024 * 100, // 100 KB
    'smart-cache.strategies.chunking.chunk_size' => (int) $itemsPerChunk,
    'smart-cache.strategies.chunking.lazy_loading' => $totalSize > 10240, // Enable if > 10 MB
]);

Chunking is essential for handling large datasets in Laravel. SmartCache's intelligent implementation makes it completely transparent while delivering significant performance and reliability benefits.
