Mike Percy created KUDU-2562: -------------------------------- Summary: Checkpoint highest legal timestamp in tablet superblock when tablet history GC deletes data Key: KUDU-2562 URL: https://issues.apache.org/jira/browse/KUDU-2562 Project: Kudu Issue Type: Improvement Components: tablet Affects Versions: 1.7.1 Reporter: Mike Percy
Checkpoint the highest legal timestamp in the tablet superblock when tablet history GC deletes data so that increasing the AHM age doesn’t expose us to inconsistent scans after a GC. This is a real edge case and is a temporary condition depending on users restarting with a changed configuration flag. However without this safety feature, users can get bad scans if they change the flag. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
