Joseph Witt commented on NIFI-3126: ----------------------------------- there are already annotations one can add to the processor which result in docs including things about CPU usage and memory. http://nifi.apache.org/docs/nifi-docs/components/org.apache.nifi/nifi-standard-nar/1.8.0/org.apache.nifi.processors.standard.CompressContent/index.html is an example for CPU We could use such things in a more prominent way than just docs. > 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 > Assignee: Otto Fowler > 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. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
