Hybrid-Cache

This NodeJS module implements a hybrid cache: a fast, in-process memory cache, backed by Redis pub-sub for invalidation. Note that no data is actually being stored in Redis.

In-memory caches are more efficient than Redis since no round-trip is necessary to access the data. However, when data changes, each copy of the cached data in all processes must be deleted, not just in the process that changes the data. Hybrid Cache uses Redis pub-sub to notify all caches in all processes of these data changes.
