20.3. Using the FileSystem Data Store Programmatically¶

20.3.1. Creating a Data Store¶

An instance of a FileSystem data store can be obtained through the normal GeoTools discovery methods, assuming that the GeoMesa code is on the classpath:

Map<String, String> parameters = new HashMap<>;
parameters.put("fs.path", "hdfs://localhost:9000/fs-root/");
org.geotools.data.DataStore dataStore = org.geotools.data.DataStoreFinder.getDataStore(parameters);

More information on using GeoTools can be found in the GeoTools user guide.

20.3.2. FileSystem Data Store Parameters¶

The FileSystem data store takes several parameters (required parameters are marked with *):

Parameter	Type	Description
`fs.path *`	String	The root path to write and read data from (e.g. s3a://mybucket/datastores/testds)
`fs.encoding`	String	The file encoding used when creating a new schema. If not specified here, it must be configured with `geomesa.fs.encoding` in the SimpleFeatureType user data. Provided implementations are `parquet` and `orc`.
`fs.read-threads`	Int	The number of threads used for queries
`fs.writer.partition.timeout`	String	Timeout for closing a partition file after write, e.g. ‘60 seconds’. This is to prevent too many open files during large write operations.
`fs.config.paths`	String	Additional Hadoop configuration resource files (comma-delimited)
`fs.config.xml`	String	Additional Hadoop configuration properties, as a standard XML `<configuration>` element
