14. Kafka Data Store

Note

GeoMesa currently supports Kafka version 0.9.x or later. However, not all features are supported for versions prior to 1.0.

The GeoMesa Kafka Data Store is an implementation of the GeoTools DataStore interface that is backed by Apache Kafka. The implementation supports the ability for feature producers to instantiate a Kafka Data Store in producer mode to persist data into the data store and for consumers to instantiate a Kafka Data Store in consumer mode to read data from the data store. The producer and consumer data stores can be run on separate servers. The only requirement is that they can connect to the same instance of Apache Kafka.

All of the Kafka-specific code for GeoMesa is found in the geomesa-kafka directory of the source distribution.
