Local Cache
Noun · Development
Definitions
An in-process cache that stores frequently accessed data in the application's own memory space, avoiding network round-trips to an external cache like Redis. Fast (nanosecond access) but not shared across instances, which introduces cache coherency concerns in distributed deployments.
In plain English: Storing frequently needed data right in the application's own memory so it does not have to ask another server for it every time.
Example: "We added a local cache with a 60-second TTL for the config endpoint — it cut Redis calls by 95% on that hot path."
