21. Lambda Data Store

The GeoMesa Lambda data store module is an implementation of the GeoTools DataStore that keeps data in two tiers, a transient tier and a persistent tier. The transient storage is backed by Apache Kafka. Any other GeoMesa data store can be used for the persistent storage, although the current module only provides configuration for Apache Accumulo. The Lambda data store is found in geomesa-lambda in the source distribution.

To get started with the Lambda data store, try the GeoMesa Lambda Quick Start tutorial.
