Mark Payne resolved NIFI-8113. ------------------------------ Fix Version/s: 1.14.0 Resolution: Fixed > Persisting status history > ------------------------- > > Key: NIFI-8113 > URL: https://issues.apache.org/jira/browse/NIFI-8113 > Project: Apache NiFi > Issue Type: New Feature > Components: Core Framework > Reporter: Simon Bence > Assignee: Simon Bence > Priority: Major > Fix For: 1.14.0 > > Time Spent: 4h > Remaining Estimate: 0h > > An alternative solution would be useful to replace/extend current in-memory > solution for storing component and node metrics. This is in order to ease > heap usage of NiFi which in case of high amount of processors (10-20k) might > be significant and also to keep system information after shutting down. > The solution should keep the data even if NiFi is stopped running and make it > possible to read it out. It should be optimised for writing data as reading > is much less frequent. > > Proposal: > * Use QuestDB as backend > * Add a new implementation for ComponentStatusRepository > * Making it interchangeable between the existing and upcoming solutions > * Provide some rollback policy in order to avoid ever-growing database -- This message was sent by Atlassian Jira (v8.3.4#803005)
