con_cache

Ensures synchronized writes per key to prevent race conditions, allowing safe concurrent updates while other keys remain accessible, as detailed in the update/3 function.

Supports global and per-item expiry with efficient checks that avoid brute-force table scans, and includes touch-on-read options for renewed item lifetimes.

Emits hit and miss events out-of-the-box, enabling easy monitoring and metric collection without custom instrumentation.

Provides low-latency access by bypassing locks for direct ETS manipulation, useful when isolation isn't required, as shown in dirty_* functions.
