MapDB (java library)

Archiviato in: java — Tag:, , , — admin @ 20:24

MapDB is embedded database engine. It provides java collections backed by disk or memory database store. MapDB has excellent performance comparable to java.util.HashMap and other collections, but is not limited by GC. It is also very flexible engine with many storage backend, cache algorithms, and so on. And finally MapDB is pure-java single 400K JAR and only depends on JRE 6+ or Android 2.1+.

What for?
> In-memory cache with expiration based on time-to-live or maximal size, Redis or EZCache replacement
> Huge indexes
> Persistent data model
> Alternative memory model if you are limited by GC
