Mike Thomsen commented on NIFI-3126:
------------------------------------
The processor depends on the Java JsonPath library, and so we're limited in how
much we can do about that unless streaming behavior is added to that library.
> A large JSON file consisting of an array of many json elements can cause an
> out of memory error if passed to SplitJSON

> Key: NIFI-3126
> URL: https://issues.apache.org/jira/browse/NIFI-3126
> Project: Apache NiFi
> Issue Type: Bug
> Components: Core Framework
> Affects Versions: 1.0.0
> Environment: RHEL 6.5 - single instance of Nifi
> Reporter: Olav Jordens
> Priority: Major
>
> Create a flowfile containing a large JSON array (large=many elements in the
> array) with many attributes. Do this in such a way that a set of flowfiles
> corresponding to the individual json elements in the array (with all the
> attributes) would require more RAM than available in your nifi JVM. Now feed
> this flowfile into a SplitJSON processor. I did not see an OOM error in the
> logs and saw very strange behavior as the whole Nifi instance hangs.
