21. FileSystem Data StoreΒΆ
The GeoMesa FileSystem data store (FSDS) provides a cost-effective, performant solution for massive OLAP-style spatial data analytics using frameworks such as Apache Spark. It utilizes modern columnar formats that enable data compression and column-based encodings for efficient OLAP queries. GeoMesa FSDS can run on local disk or on distributed object stores such as Amazon S3. This enables users to realize cost savings through the utilization of elastic compute resources instead of dedicated servers.
The FileSystem datastore can be used to ETL new data into a filesystem or wrap existing file system storage directories using a GeoMesa converter. In both modes the user must provide a defined partition scheme describing the layout of the directory structures.
