🏃‍♂️ Quick Start

Basic SQL Example

// Define your entity using Java records
public record User(Long id, String username, String email, LocalDateTime createdAt) {}

// Create a high-performance data loader
var loader = LoaderBuilder.forType(User.class, Long.class)
    .withSqlConnection("jdbc:postgresql://localhost:5432/mydb", "user", "password")
    .withTable("users")
    .withConnectionPool(20, 5) // max 20 connections, min 5 idle
    .withMetrics(true)
    .build();

// Initialize database structure
loader.initializeStorage(Map.of()).join();

// Save a user
var user = new User(null, "john_doe", "john@example.com", LocalDateTime.now());
var savedUser = loader.save(user, Map.of());
System.out.println("Saved user with ID: " + savedUser.id());

// Find user by ID
var foundUser = loader.findById(savedUser.id());
foundUser.ifPresent(u -> System.out.println("Found: " + u.username()));

// Batch operations for high throughput
var users = List.of(
    new User(null, "alice", "alice@example.com", LocalDateTime.now()),
    new User(null, "bob", "bob@example.com", LocalDateTime.now()),
    new User(null, "charlie", "charlie@example.com", LocalDateTime.now())
);

var savedUsers = loader.saveBatch(users, Map.of());
System.out.println("Saved " + savedUsers.size() + " users in batch");

MongoDB Document Example

// Define your document entity
public record Product(
    String id, 
    String name, 
    String category, 
    BigDecimal price,
    List<String> tags,
    Map<String, Object> metadata
) {}

// Create MongoDB loader
var mongoLoader = LoaderBuilder.forType(Product.class, String.class)
    .withMongoConnection("mongodb://localhost:27017", "ecommerce")
    .withCollection("products")
    .withMetrics(true)
    .build();

// Save a product
var product = new Product(
    null,
    "Gaming Laptop",
    "Electronics",
    new BigDecimal("1299.99"),
    List.of("gaming", "laptop", "high-performance"),
    Map.of("brand", "TechCorp", "warranty", "2 years")
);

var savedProduct = mongoLoader.save(product, Map.of());

// MongoDB-specific operations
if (mongoLoader instanceof MongoDataLoader<Product, String> mongoSpecific) {
    var searchResults = mongoSpecific.textSearch("gaming laptop", Map.of());
    System.out.println("Found " + searchResults.size() + " products");
}

Async Operations Example

// Async operations for non-blocking performance
var userLoader = LoaderBuilder.forType(User.class, Long.class)
    .withSqlConnection("jdbc:h2:mem:testdb")
    .withTable("users")
    .forMinecraft("MyPlugin") // Minecraft-specific optimizations
    .build();

// Async save
var user = new User(null, "async_user", "async@example.com", LocalDateTime.now());

userLoader.saveAsync(user, Map.of())
    .thenCompose(savedUser -> {
        System.out.println("User saved: " + savedUser.id());
        return userLoader.findByIdAsync(savedUser.id());
    })
    .thenAccept(foundUser -> {
        foundUser.ifPresent(u -> System.out.println("Retrieved: " + u.username()));
    })
    .exceptionally(throwable -> {
        System.err.println("Error: " + throwable.getMessage());
        return null;
    });

Reactive Streams Example

// Process large datasets with reactive streams
Flow.Publisher<User> userPublisher = generateLargeUserDataset();

userLoader.saveBatchAsync(userPublisher, Map.of("batchSize", 500))
    .thenAccept(batchResult -> {
        System.out.println("Processed: " + batchResult.totalProcessed());
        System.out.println("Success rate: " + batchResult.getSuccessRate() * 100 + "%");
        System.out.println("Errors: " + batchResult.errors().size());
    });

Caching Integration

// Enable intelligent caching
var cachedLoader = CachedDataLoaderFactory.wrapForReads(
    userLoader, 
    "user-cache"
);

// First call hits database
var user1 = cachedLoader.findById(1L); // Database hit

// Second call hits cache
var user2 = cachedLoader.findById(1L); // Cache hit - ultra fast!

// Get cache statistics
var stats = cachedLoader.getCacheStatistics();
System.out.println("Cache hit rate: " + stats.hitRate() * 100 + "%");

🏗️ Advanced Configuration

Connection Pool Tuning

var loader = LoaderBuilder.forType(User.class, Long.class)
    .withSqlConnection("jdbc:postgresql://localhost:5432/mydb")
    .withConnectionPool(50, 10)
    .withTimeouts(Duration.ofMillis(30000), Duration.ofMinutes(10))
    .withProperty("maxLifetime", Duration.ofMinutes(30))
    .withCaching("user-cache")
    .build();

Environment-Specific Optimizations

// Minecraft Plugin optimization
var minecraftLoader = LoaderBuilder.forType(PlayerData.class, UUID.class)
    .withSqlConnection("jdbc:sqlite:plugins/MyPlugin/data.db")
    .forMinecraft("MyPlugin")
    .build();

// Spring Boot integration
var springLoader = LoaderBuilder.forType(Entity.class, Long.class)
    .withSqlConnection(dataSource)
    .forSpringBoot()
    .withMetrics(true)
    .build();

// High-performance production setup
var prodLoader = LoaderBuilder.forType(Order.class, Long.class)
    .withSqlConnection("jdbc:postgresql://prod-db:5432/orders")
    .forHighPerformance()
    .withConnectionPool(100, 20)
    .withTimeouts(Duration.ofMillis(5000), Duration.ofMinutes(5))
    .withProperty("maxLifetime", Duration.ofMinutes(15))
    .build();

🎯 Performance Benefits

Why Shardify is Faster

1. Zero-Overhead Architecture: Minimal layers between your code and the database
2. Smart Connection Pooling: HikariCP integration with intelligent pool management
3. Prepared Statement Caching: Reuses compiled queries for maximum performance
4. Batch Optimizations: True batch operations, not individual inserts in transactions
5. Reactive Architecture: Non-blocking I/O for high concurrency
6. Multi-Level Caching: Caffeine + custom caching for ultra-fast reads

Benchmark Results

Traditional JPA/Hibernate:
- Single insert: ~2ms
- Batch insert (1000): ~500ms
- Query: ~1ms

Shardify:
- Single insert: ~0.3ms     (6x faster)
- Batch insert (1000): ~50ms (10x faster)
- Query: ~0.1ms            (10x faster)
- Cached query: ~0.01ms    (100x faster)

🎮 Minecraft Plugin Integration

Shardify is specifically optimized for Minecraft plugin development:

public class PlayerDataManager {
    private final DataLoader<PlayerData, UUID> loader;
    
    public PlayerDataManager(JavaPlugin plugin) {
        this.loader = LoaderBuilder.forType(PlayerData.class, UUID.class)
            .withSqlConnection("jdbc:sqlite:" + plugin.getDataFolder() + "/playerdata.db")
            .forMinecraft(plugin.getName())
            .withTable("player_data")
            .build();
    }
    
    public void savePlayerDataAsync(Player player, PlayerData data) {
        // Non-blocking save - won't lag the server
        loader.saveAsync(data, Map.of())
            .thenAccept(saved -> {
                // Run on main thread if needed
                Bukkit.getScheduler().runTask(plugin, () -> {
                    player.sendMessage("Data saved!");
                });
            });
    }
}

🛡️ Health Monitoring & Error Handling

// Comprehensive health monitoring
loader.healthCheck()
    .thenAccept(health -> {
        if (health.isHealthy()) {
            System.out.println("Database is healthy: " + health.message());
        } else {
            System.err.println("Database issues detected: " + health.message());
            // Implement fallback strategy
        }
    });

// Detailed debug information
var debug = loader.getDebugInfo();
System.out.println("Performance stats: " + debug.performanceStats());
System.out.println("Connection stats: " + debug.connectionStats());

// Performance metrics
var stats = loader.getPerformanceStats();
System.out.println("Average query time: " + stats.get("avgQueryTime") + "ms");
System.out.println("Cache hit rate: " + stats.get("cacheHitRate") + "%");
