Andre F de Miranda commented on NIFI-4098:
------------------------------------------
A change to upstream library has been proposed. The change will allow ParseCEF
to call ParCEFone's CEFParser constructor providing a pre-initiated shared Bean
Validator. Tests in real life scenarios suggest a significant performance
improvement despite the validation of every individual message.
Once an updated version of the library is made available, a PR with the NiFi
code will be submitted
> ParseCEF performance issues

> Key: NIFI-4098
> URL: https://issues.apache.org/jira/browse/NIFI-4098
> Project: Apache NiFi
> Issue Type: Bug
> Affects Versions: 1.1.0, 1.2.0, 1.1.1, 1.3.0
> Reporter: Andre F de Miranda
> Assignee: Andre F de Miranda
>
> Under certain circumstances the use of ParseCEF may cause bottle necking on
> relationships.
> Using the yourkit profiler, it seems the main reason for the slowness is
> caused by the upstream library use of Bean validation to validate the CEF
> extension fields.
