Just had a new look and ran a workflow to test the processor. Few remarks
even though I am not familiar with Ignite... First, I am not sure to see how I
can check the content of what is sent to Ignite, do you have recommendation
about that?
Then, it seems that if I don't provide a configuration file, the processor
is running an embedded Ignite cache but in that case I am not sure of what is
the interest for the user. Even with a local Ignite node running it does not
seem to connect to it, normal?
Other remark, in the logs, I see some periodic status about the Ignite
instance

I don't know if it makes sens to have this kind of logs in NiFi logs,
thoughts?
Regarding the transit URI of the provenance event, I am not convinced. Is
there a way to get IP/port of the node the processor is connected to and use
this information in the event? (like, I believe, it is done in Kafka processors)
I believe there is also some kind of issues when stopping the processor: it
doesn't seem to stop gracefully and I get some stack traces when trying to run
it again... in the end, none of the incoming flow files are ingested. Here is
the stack trace if it helps
