EDA.Cache.Evictor (EDA v0.3.0)

Copy Markdown View Source

Periodic LRW (Least Recently Written) evictor for caches with max_size.

Shadow ETS tables track write timestamps only for caches that have a configured max_size. Caches without max_size incur zero overhead.

Every @interval ms, the evictor checks each evictable cache and removes the oldest entries when the main table exceeds its limit.

Example

config :eda,
  cache: [
    users: [max_size: 100_000]
  ]
