Description

This is a DIH Cache implementation using Map DB version 1.0.2. Map DB is a pure Java key-value store that supports both file-based caches and memory-based caches (both on- and off-heap). See http://www.mapdb.org/. MapDB is ASL2.0 licensed, so unlike the BDB-JE cache impl (SOLR-2613), this one could potentially be committed.

This does not perform nearly as well as the BDB-JE cache, but I imagine it is fast enough for a lot of uses.
