maintain

public void maintain()

By default, Caffeine does not perform cleanup and evict values "automatically" or instantly after a value expires. Instead, it performs small amounts of maintenance work after write operations or occasionally after read operations if writes are rare. If your cache is high-throughput then you don't have to worry about performing cache maintenance to clean up expired entries and the like. If your cache is read and written to rarely, you may wish to leverage an external thread, that calls Cache.cleanUp() when appropriate.
