pub struct SharedPlanCache { /* private fields */ }Expand description
Shared LRU cache for non-CALL source-string execution plans.
The cache is caller-owned so embedders can share one
Arc<SharedPlanCache> across short-lived sessions executing against the
same graph. Keys include graph identity, schema epoch, procedure-registry
epoch, source text, implementation-defined caps, and the optimizer
index-selection mode, matching every setting currently baked into a lowered
or optimized plan. Procedure-CALL-containing plans remain owned by
crate::CallPlanCache.
Implementations§
Sourcepub fn new(capacity: NonZeroUsize) -> Self
pub fn new(capacity: NonZeroUsize) -> Self
Create an empty shared source-plan cache with the given entry capacity.
Sourcepub fn stats(&self) -> SharedPlanCacheStats
pub fn stats(&self) -> SharedPlanCacheStats
Return a snapshot of the cache counters.
