For use cases with lots of flushing and > compacting, this might be desirable to prevent cache misses and maximize the > effective utilization of total block cache capacity. > The first option, {{hbase.rs.cacheblocksonwrite}}, will make it so we > pre-cache blocks as we are writing out new files. > The second option, {{hbase.rs.evictblocksonclose}}, will make it so we evict > blocks when files are closed. -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
