GeoMesa Spark allows for execution of jobs on Apache Spark using data stored in GeoMesa, other GeoTools  DataStore s, or files readable by the GeoMesa converter library. The library allows creation of Spark  RDD s and  DataFrame s, writing of Spark  RDD s and  DataFrame s to GeoMesa Accumulo and other GeoTools  DataStore s, and serialization of  SimpleFeature s using Kryo. Architecture GeoMesa Spark provides capabilities to run geospatial analysis jobs on the distributed, large-scale data processing engine  Apache Spark . It provides interfaces for Spark to ingest and analyze geospatial data stored in GeoMesa data stores. GeoMesa provides Spark integration at several different levels. At the lowest level is the  geomesa-spark-jts  module (see  Spark JTS ), which contains user-defined spatial types and functions. This module can easily be included in other projects that want to work with geometries in Spark, as it only depends ...
