[GitHub] [pinot] richardstartin opened a new issue #7411: User provided JsonPaths should be validated/rejected at startup

[GitBox]

richardstartin opened a new issue #7411:
URL: https://github.com/apache/pinot/issues/7411


   In a profile from a system where invalid JSON paths were configured, a lot 
of time (> 20%) was spent during ingestion throwing at least one JSON path 
validation exception per row. The operator of a properly configured deployment 
should ensure that JSON paths are valid, but this is a poor failure mode and it 
would be better to reject the transformation and log very clearly that the JSON 
path failed validation and won't be applied.
