16.4. Using the Kudu Data Store Programmatically

16.4.1. Creating a Data Store

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

Map<String, Serializable> parameters = new HashMap<>();
parameters.put("kudu.master", "localhost");
parameters.put("kudu.catalog", "geomesa");
org.geotools.data.DataStore dataStore =
    org.geotools.data.DataStoreFinder.getDataStore(parameters);

16.4.2. Kudu Data Store Parameters

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

Parameter	Type	Description
kudu.master *	String	The host name of the Kudu master server
kudu.catalog *	String	The name of the GeoMesa catalog table
kudu.credentials	String	Kudu client authentication credentials
kudu.worker.threads	String	Number of worker threads used by the Kudu connection
kudu.boss.threads	String	Number of boss threads used by the Kudu connection
kudu.client.stats.disable	Boolean	Disable Kudu client statistics
geomesa.security.auths	String	Comma-delimited superset of authorizations that will be used for queries
geomesa.query.audit	Boolean	Audit queries being run. Queries will be written to a log file
geomesa.query.timeout	String	The max time a query will be allowed to run before being killed. The timeout is specified as a duration, e.g. 1 minute or 60 seconds
geomesa.query.threads	Integer	The number of threads to use per query
geomesa.query.loose-bounding-box	Boolean	Use loose bounding boxes - queries will be faster but may return extraneous results
geomesa.stats.generate	Boolean	Toggle collection of statistics (currently not implemented)
geomesa.query.caching	Boolean	Toggle caching of results
