Foundry.Context.Cache (foundry v0.1.3)

ETS-backed cache for module context data.

Provides get_or_compute/3 to cache expensive operations like SparkMeta.walk/1 results.

This is a Phase 1 stub using process-local caching. Will be upgraded to Nebulex L1 (Hex dependency) in Phase 3+ when Nebulex is added.

Summary

Functions

get_or_compute(key, ttl \\ :infinity, fun)

Get a cached value or compute it if not present.

Functions

get_or_compute(key, ttl \\ :infinity, fun)

Get a cached value or compute it if not present.

CONCURRENCY NOTE: This is a best-effort cache (last-write-wins on race). Two concurrent calls with a cold cache will both compute and both put. This is acceptable because: (1) SparkMeta.walk/1 is idempotent, (2) test environment is single-threaded with async: false, (3) real projects are read-heavy on modules. If atomicity becomes critical, add a lock.
