> StandardProcessSession.isSpuriousRouteEvent() performance
> ---------------------------------------------------------
>
> Key: NIFI-3277
> URL: https://issues.apache.org/jira/browse/NIFI-3277
> Project: Apache NiFi
> Issue Type: Improvement
> Reporter: Bryan Rosander
> Assignee: Bryan Rosander
> Priority: Minor
>
> StandardProcessSession.isSpuriousRouteEvent() currently creates a
> Relationship from a builder and loops over all checkpoint records for every
> route provenance event generated by the processor.
> This takes nontrivial time and can be mitigated by caching the Relationships
> and creating a uuid -> StandardFlowFileRecord map on-demand.
