Hi James,
Sorry for the lack of documentation - we'll try to get something
better together. In the meantime, hopefully this will help:
To get a feature name to show up in the kafka data store in
geoserver, you have to create a schema using a kafka producer data
store. This would usually happen outside of geoserver, in some other
process. The following code snippet shows how you get a kakfa
producer:
Map params = new HashMap();
params.put("brokers
", "my-kafka-brokers");
params.put("zookeepers", "my-zookeepers");
params.put("isProducer", true); // important - this specifies that
you will be writing features
DataStore dataStore =
org.geotools.data.DataStoreFinder.getDataStore(params);
SimpleFeatureType myType =
org.locationtech.geomesa.utils.interop.SimpleFeatureTypes.createType("myType",
"name:String,*geom:Point:srid=4326");
dataStore.createSchema(myType);
You should now be able to see the feature name in geoserver,
assuming you use the same connection properties. In order to view
live features, you will need to write them using the normal GeoTools
API using the above producer dataStore. Let me know if you have any
questions about that, but there are lots of example on the
getools/geoserver sites.
One note: the kafka data store is meant for ephemeral features - if
you restart geoserver you will lose any features you have already
written.
Thanks,
Emilio

Good morning,
I’m newbie to Geomesa and I’m attempting to
use geomesa-kafka tool to create “featureName” on “Kafka Data
Source” on GeoServer.
I was able to build and deploy
geomesa-kafka-geoserver-plugin-accumulo1.5.1.0-rc-5-SNAPSHOT-geoserver-plugin-jar
into GeoServer successfully.
From GeoServer UI, I can add a new data
store as “Kafka Data Store”. However, I don’t see any
FeatureName is showed up to associate with Kafka DS to
publish.
Since there is no documentation available
on Geomesa-kafka, please provide us with more information how
to publish FeatureName for each Kafka topic.
Thanks.
