Hello, I have NiFi flow with EvaluateJsonPath that read a content of FlowFile with json to Data attribute. But numeric values of json are changed, i.e.: GenerateFlowFile { "Amount1": 999999999999999999.99, "Amount2": 999999999.99 } -> EvaluateJsonPath Data $ -> Data {"Amount1":1.0E18,"Amount2":9.9999999999E8} How do I stop NiFi from rounding off and changing json numbers? Tested on NiFi 1.15/1.19. Thanks.

Hello, My NiFi flow has two process groups that process data from kafka: main - ~20 processors that processes 100 json messages per second support - ~900 processors that processes 1-2 json messages in a day When the main group is running (started) without message processing the CPU load is ~5%. When the support group is additionally started the CPU load is ~20% (without messages). In addition the main group handles messages with 1-2 sec latency if the support group is not running, but latency increases dramatically (x10-20) if i just start the support group. Is it possible to set additional priorities for the main group or somehow configure the nifi scheduler? Thanks.
