I vote -1 because I feel that HBASE-28596 should be included in 2.6.3. There is an open PR to accomplish this: https://github.com/apache/hbase/pull/6508. This will fix a performance regression that was introduced in 2.6.0 by HBASE-27474. The regression is described in HBASE-29012, but to summarize: logic was added so that we don't cache blocks that exist within a reference or a link. This is a significant issue. At Hubspot we had to apply the patch from the PR to our fork in order to have acceptable performance.
