Pierre Villard resolved NIFI-11106.
-----------------------------------
Resolution: Feedback Received
Apache NiFi 1.x is no longer maintained and no new release is planned on the
1.x release line. Marking as resolved as part of a cleanup operation. Please
open a new one with an updated description if this is still relevant for NiFi
2.x.
> QueryRecord can fail to rollback sessions on commit failure.
> ------------------------------------------------------------
>
> Key: NIFI-11106
> URL: https://issues.apache.org/jira/browse/NIFI-11106
> Project: Apache NiFi
> Issue Type: Bug
> Components: Extensions
> Affects Versions: 1.14.0, 1.13.2, 1.15.3, 1.17.0, 1.16.3, 1.18.0, 1.19.1
> Reporter: Kevin Doran

> It appears that going back to at least NiFi 1.13.2, there are some
> configurations of QueryRecord that can result flowfiles to be not closed
> properly prior to attempting to commit a session. This causes session commit
> to fail, as a a flow file cannot be written while it is still open for
> reading. These show up as uncaught exceptions in NiFi logs (see below).
> Additionally, failed session commits should be rolled back and reprocessed,
> however, some of these QueryRecord commit failures do not get rolled back
> properly. When this occurs, the content of the flowfile is stuck, uncommitted
> so it will not reach downstream processors and not rolled back so that it
> will land back in the QueryRecord input queue to be reprocessed. This can
> result in data loss for the contents of the stuck flowfile.
> Specifically this has been observed with QueryRecord, GrokReader, and
> FreeFormTextRecordSetWriter.
> *Attached is an example configuration of QueryRecord (including record
> reader/writer) that can result in this behavior.*
> During the time observed, data volume was about 40-78 million records per
> hour, with the uncaught exceptions only occasionally occurring (between 0 and
> 10 times per hour). Of those uncaught exceptions, not all resulting in data
> loss / failed rollback, so that is even more rare.
> *Data characteristics:*
> * For the given QueryRecord config that has include and exclude queries, both
> queries are expected to match some lines in the input flowfile.
> * The flowfile is also expected to contain some unmatched lines, such as
> empty lines, lines of text that don't match either query, or corrupted /
> binary lines that don't decode to ascii intermixed with plaintext lines.
> Example data can be provided upon request.
> Here are the stack traces for how this issue appears on NiFi 1.16.1:
