Re: [geomesa-users] Kafka Datastore Nifi Component:

["Stone, Damon" <dstone@xxxxxxxxxxxxxxx>]

Hi Andrew,

Indeed in would make more sense for a Put component to act as a producer, perhaps even still more sense to obscure the isProducer parameter all together and have separate Put and Get components.

 Thanks for the help!

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.
