David Handermann updated NIFI-11825:
------------------------------------
Priority: Major (was: Minor)
> QueryRecord processor; failure to close resources contributes to excess
> memory usage
> ------------------------------------------------------------------------------------
>
> Key: NIFI-11825
> URL: https://issues.apache.org/jira/browse/NIFI-11825
> Project: Apache NiFi
> Issue Type: Bug
> Reporter: Paul Grey
> Assignee: Paul Grey
> Priority: Major
> Time Spent: 40m
> Remaining Estimate: 0h
>
> The QueryRecord processor includes a cache of RecordSchema / CachedStatement
> mappings (to improve performance). The CalciteJdbc41PreparedStatement /
> CalciteResultSet implementation of CachedStatement is holding a reference to
> the ResultSet when it is inserted into the cache. In the case of large
> ResultSets (for example, from record-oriented FlowFiles with many records),
> this has the potential to adversely impact memory available to the NiFi
> process.
> The remediation is to use a "try with resources" construct during processing
> of the result set, to ensure that the result set is closed after it is
> processed.
