: Is it possible to use solr caches such as query cache , filter cache : and document cache from external caching system like memcached as it : has several advantages such as centralized caching system and reducing the : pause time of JVM 's garbage collection as we can assign less memory to : jvm .
No. The purpose of those solr caches is to "micro-cache" those objects that are used at a very low level in memory. In an external cache system network overhead and object serialization become a factor in performance. using them in a "micro" cache aspect doesn't make sense -- at that point you're probably better off using something like an HTTP proxy cache to do "macro" caching at the level of the entire HTTP request/response. -Hoss
