Can NiFi be used in the place for simple Spring boot REST API's

[#1]

Is it a good idea to use NiFI in the place for simple Spring boot REST API's.

Nifi is meant for moving data, it can get/send data to and from APIs.

It will not be great to just let it sit there an try to call it whenever you need a bit of data.

Kafka may be a closer fit for this.

Thanks you for the reply ! i also had the same understanding. As per my understanding, its meant for ingestion use-cases and not a great fit to replace the normal REST API's with lot of business logics. Just wanted to clear my understanding.
