[infinispan-issues] [JBoss JIRA] Resolved: (ISPN-815) Clone caches should be created and started much faster

Clone caches should be created and started much faster ------------------------------------------------------ Key: ISPN-815 URL: https://jira.jboss.org/browse/ISPN-815 Project: Infinispan Issue Type: Bug Components: Configuration Affects Versions: 4.2.0.CR2 Reporter: Galder Zamarreño Assignee: Galder Zamarreño Fix For: 4.2.0.CR3, 4.2.0.Final Attachments: CacheStartProfile.png, StressCacheCreationTest.java We must be faster creating caches that are just simply copies of the same configuration. Creating 500 caches of the default cache configuration takes around 4 seconds. Creating 1000 caches takes around 10 seconds. This is too slow. As shown in the profiler screenshot, calling componentRegistry.registerComponent(spi, AdvancedCache.class); is quite expensive. The start procedure is also quite expensive, specially due to some reflection going on there. IMO, we need fast way to clone caches. IOW, if you create Cache A based on config default config, creating/starting Cache B based on default config should be extremely fast. Simply duplicate objects and set them in the right state. This is of particular importance in 2LC use cases where each entity/collection is stored in a separate cache and these are generally created on startup by the Hibernate Session Factory. Check the linked user forum post for some feedback from a 2LC user.
