> Cacheing of parsed queries is pretty tightly coupled to how the query index is implemented so separating them out might be trickier The current "solr monitor" PR avoids this problem entirely by just not using the monitor and internal caches altogether. Really the best part of the monitor module is the presearcher with its various optimizations. One of the problems is that to go to it you have to go through the coarse synchronization which is done to update the naive cache and index at the same time. The linked PR does no such synchronization and manages its own caffeine cache which is optimistically updated. Versioning is used to make sure the index matches the cache, and if not, the cache is updated (assuming cache version is lower). -- This is an automated message from the Apache Git Service.
