15.2. Using the Bigtable Data Store Programmatically

15.2.1. 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);

15.2.2. 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
