Expand description
Query plan cache for avoiding repeated optimization.
This module provides a simple LRU cache for compiled physical plans. When the same logical plan is executed multiple times, the cached physical plan can be reused, skipping the optimization phase.
Structs§
- Plan
Cache - LRU cache for compiled physical plans.
Functions§
- compute_
plan_ fingerprint - Computes a fingerprint (hash) for a logical plan. Plans with the same structure will have the same fingerprint.
