Change subject: engine: Introducing using of Infinispan cache at TimeoutBase ...................................................................... engine: Introducing using of Infinispan cache at TimeoutBase The TimeoutBase was used for the following purpose: 1. The audit event which has expiration time was put to it internal cache 2. If the same event was tried to put again and it is expired, it was written to DB Sound simple but a following implementation contains: 1. Memory leak - if we never tried to put event when it was already expired, internal cache never will be cleared 2. Restart - restart in the middle , event will be never send to DB Solution: I decided to use infinispan cache, from now if event has expiration time and it not contains in cache it will be written to DB. If event is contains in cache it will be skipped. The cache has putIfAbsent() API which is similar to ConcurrentHashMap API, the entries are added to cache with lifespan and will be cleared automatically by cache.
