Advanced Performance

Advanced performance optimization techniques for high-throughput applications.

Zero-Copy Row Deserialization

Minimize allocations by borrowing string data directly from database rows instead of copying.

RowRef Trait

The RowRef trait provides zero-copy access to row data.

FromRowRef Trait

Deserialize structs that borrow data from the row.

Benefits

  • • Zero allocations for string fields
  • • Reduced memory pressure
  • • Faster deserialization
  • • Better cache locality

Trade-offs

  • • Borrowed data tied to row lifetime
  • • May need to_owned() for storage
  • • Complex lifetime annotations

Batch & Pipeline Execution

Reduce database round-trips by combining multiple operations.

Batch Builder

Combine multiple INSERT statements into a single multi-row INSERT.

Pipeline Builder

Execute multiple queries in sequence with minimal overhead.

Query Plan Caching

Cache execution plans with performance hints and automatic metrics tracking.

ExecutionPlanCache

Plan Hints

Provide optimization hints to the query executor.

Performance Analysis

Type-Level Filters

Diesel-style zero-cost filter abstractions with stack allocation.

And5, Or5, etc.

DirectSql Trait

Generate SQL directly without intermediate Filter enum.

Slice-Based IN Filters

Zero-allocation IN clauses using borrowed slices.

Connection Pool Optimization

Optimize connection pool settings for your workload.
