Serve repeated reads from an in-memory or pluggable cache, opted in per query.

By PrismaPostgreSQLMongoDB

What it does

An opt-in caching middleware built on the intercept hook. Annotate a query with a TTL and identical plans are answered from the cache without touching the driver. Ships an in-memory LRU store and a CacheStore interface for Redis or other backends. Works on PostgreSQL and MongoDB runtimes.
