Istvan Toth created PHOENIX-6965: ------------------------------------ Summary: UngroupedAggregateRegionScanner.insertEmptyKeyValue() generates too many cells Key: PHOENIX-6965 URL: https://issues.apache.org/jira/browse/PHOENIX-6965 Project: Phoenix Issue Type: Bug Components: core Affects Versions: 5.1.3, 5.2.0 Reporter: Istvan Toth Assignee: Istvan Toth
UngroupedAggregateRegionScanner.insertEmptyKeyValue() is supposed to generate one empty cell for each timestmap. However, it never adds the generated timestamp to the controll map, and generated an empty cell for each existing cell. IIRC, these are all set to the the RS an d to WAL, and are only consolidated in the memstore, leading to a lot of wasted cpu, memory, io, and network resources. -- This message was sent by Atlassian Jira (v8.20.10#820010)
