Configuration Tips
Batch Size Optimization
Optimal batch sizes depend on your workload:
// For high-throughput writes const batch_size: u32 = 10000; // For low-latency operations const batch_size: u32 = 100; // For mixed workloads const batch_size: u32 = 1000;
Memory Pool Sizing
Configure memory pools based on your data size:
// Large datasets (> 1GB) const memory_pool_size: usize = 8 * 1024 * 1024 * 1024; // 8GB // Medium datasets (100MB - 1GB) const memory_pool_size: usize = 1 * 1024 * 1024 * 1024; // 1GB // Small datasets (< 100MB) const memory_pool_size: usize = 256 * 1024 * 1024; // 256MB
