Hi Damon,
Yes, the GeoMesa Nifi component will do two things:
1. Insert metadata into Zookeeper about the topic
2. Create a kafka topic based on the sft name
The Nifi component will use the same params as the Kafka Data
Store: http://www.geomesa.org/documentation/user/kafka/usage.html
Note that you need to set the "isProducer" field to "true" in
order to write to the kafka datastore from nifi. I opened up a
ticket to force this to "true" since it doesn't make sense for it
to be false for a "Put" processor.
Let us know if you have any questions!

Hello,
We are trying to use
the Geomesa Nifi component to write to a topic in
Kafka that doesn't yet exist.
We would like to
understand if the component will create the schema
as defined by the sft and converter supplied as
parameters, or if the schema needs to be created
ahead of time (outside of Nifi) either
programmatically or via CLI.
Any insight into this
would be a great help.
