Matt Burgess updated NIFI-6820: ------------------------------- Fix Version/s: 1.13.0 > If Processor adjusts a counter but does not interact with any FlowFiles, the > counter isn't updated > -------------------------------------------------------------------------------------------------- > > Key: NIFI-6820 > URL: https://issues.apache.org/jira/browse/NIFI-6820 > Project: Apache NiFi > Issue Type: Bug > Components: Core Framework > Reporter: Mark Payne > Assignee: Hsin-Ying Lee > Priority: Major > Labels: beginner, easyfix, newbie > Fix For: 1.13.0 > > Time Spent: 1h 10m > Remaining Estimate: 0h > > If a Processor calls `ProcessSession.adjustCounter` and passes `false` for > the `immediate` argument, the adjustment for the counter should be maintained > by the ProcessSession. Then, when (if) the session is committed, the counter > should actually be updated. However, if the Processor never interacts with > any FlowFiles (never calls `get()` or `create()`), then the counter never > gets updated. > This appears to be due to the fact that in the `checkpoint` method, > `StandardProcessSession` checks if `records.isEmpty()` and if so returns. In > such a case, it needs to first ensure that it transfers the counters to the > checkpoint before returning. -- This message was sent by Atlassian Jira (v8.3.4#803005)
