Joe Skora created NIFI-3039: ------------------------------- Summary: Provenance Repository - Fix PurgeOldEvent and Rollover Size Limits Key: NIFI-3039 URL: https://issues.apache.org/jira/browse/NIFI-3039 Project: Apache NiFi Issue Type: Bug Components: Core Framework Affects Versions: 0.7.1, 1.0.0, 1.1.0, 0.8.0 Reporter: Joe Skora Assignee: Joe Skora
Current {purgeOldEvents} logic triggers cleanup when 90% of space is used, but it only removes one file if usage is under 100%, causing thrashing around 100% usage. In testing, cleanup up to 70% after hitting 90% makes the system run more smoothly. Also, {rollover} will not trigger cleanup unless 110% of the allowed space is in use, changing this to 100% also make a difference in testing. Before these changes, a test system that generates huge amounts of provenance would become unstable and stop processing provenance until restarted. With these changes, the system consistently recovers even under heavy load. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
