arenger edited a comment on issue #3414: NIFI-5900 Add a SplitLargeJson processor URL: https://github.com/apache/nifi/pull/3414#issuecomment-485907212 @ottobackwards Yeah that sounds good. On which branch did you make the updates to simple-syslog5424? I could pull those into a new branch that adds a new `FilterJson` processor backed by `JsonSurfer`. I created a [NIFI-5900-JsonSurfer](https://github.com/arenger/nifi/blob/NIFI-5900-JsonSurfer/nifi-nar-bundles/nifi-standard-bundle/nifi-standard-processors/src/main/java/org/apache/nifi/processors/standard/SplitLargeJson.java) branch with a prototype (messy approximation) of what it could look like. It's still called "SplitLargeJson" there, but I'd rename it. I also updated the [unit tests](https://github.com/arenger/nifi/blob/NIFI-5900-JsonSurfer/nifi-nar-bundles/nifi-standard-bundle/nifi-standard-processors/src/test/java/org/apache/nifi/processors/standard/TestSplitLargeJson.java) so you could see how the processor would work. I ran the same memory tests on that processor and it behaves as advertised (i.e. doesn't create an in-memory DOM while processing): <img width="257" alt="json-surfer-memory" src="https://user-images.githubusercontent.com/1693576/56603698-36e29c80-65ce-11e9-9dbb-bc98a666380f.png";> ... so that's good. How about I create a simpler PR for adding a new `FilterJson` processor, and we can discuss this further as part of that PR?
