Summary: Normalizer can skip picking presplit regions while preparing merge plans Key: HBASE-27667 URL: https://issues.apache.org/jira/browse/HBASE-27667 Project: HBase Issue Type: Improvement Components: Normalizer Reporter: Rajeshbabu Chintaguntla Assignee: Rajeshbabu Chintaguntla Fix For: 2.6.0, 3.0.0-alpha-4, 2.5.4 Normalizer can be used to merge the regions which become emtpy post TTL expiry. But it's picking the presplit regions as well. We can skip picking presplit regions while preparing the merge plans by looking at the number of storefiles compared to size. Presplit regions have zero storefiles where as the TTL expired regions have 1 storefile with zero size. -- This message was sent by Atlassian Jira (v8.20.10#820010)
