* Cache: Add maxEntrySize config. The idea is this makes it more feasible to cache query types that can potentially generate large result sets, like groupBy and select, without fear of writing too much to the cache per query. Includes a refactor of cache population code in CachingQueryRunner and CachingClusteredClient, such that they now use the same CachePopulator interface with two implementations: one for foreground and one for background. The main reason for splitting the foreground / background impls is that the foreground impl can have a more effective implementation of maxEntrySize. It can stop retaining subvalues for the cache early. * Add CachePopulatorStats. * Fix whitespace. * Fix docs. * Fix various tests. * Add tests. * Fix tests. * Better tests * Remove conflict markers. * Fix licenses. |
