README

Read-only mirror. hydrakit/cache is developed in hydra-foundation/hydra under packages/cache, and republished here on every push. A commit pushed to this repository is overwritten by the next one; issues are disabled for that reason, and a pull request opened here cannot be merged. Both belong upstream.

A key/value store with expiry behind one contract, in two implementations: Redis, shared by every process that connects to it, and an in-memory array for tests and single-process tooling. The counter methods are why the contract is narrow — increment() adds to a key and opens its expiry window on the first hit, as one atomic step, and never re-arms that window afterwards. Anything budgeting per client therefore counts against a window measured from the first request rather than one a steady stream can hold open indefinitely. ArrayStore is deliberately not a fallback for an unreachable Redis: it is per-process, so behind a worker pool it would give each worker its own counters and multiply every limit by the pool size.
