Re: enforce run only in promary node $ multiple primary node

Tijo, To give you some information on your second question, you can design your flow to redistribute the flowfiles coming out of your processors to other nodes in the cluster for processing. There are several examples on how this on various blogs/email lists/etc, and I just grabbed one for refere

ETL processors for NiFi

Hello All, I am currently developing an ETL pipeline and I am using Apache NiFi for this task. I would like to know if there is any processor that help with the following use case: I am consuming from Kafka and based on some attributes in the message then I am updating the database with the data.

Re: ETL processors for NiFi

Re: UI: feedback on the processor 'color' in NiFi 1.0
