10.2. Using the Bigtable Data Store Programmatically

10.2.1. Creating a Data Store

An instance of a Bigtable data store can be obtained through the normal GeoTools discovery methods, assuming that the GeoMesa code is on the classpath. The Bigtable data store also requires that an hbase-site.xml be located on the classpath; the connection parameters for the Bigtable data store are obtained from this file. For more information, see Connecting to Cloud Bigtable.

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

10.2.2. Bigtable Data Store Parameters

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

Parameter	Type	Description
bigtable.catalog *	String	The name of the GeoMesa catalog table (previously bigtable.table.name)
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

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