16.2. Using the Cassandra DataStore Programmatically

16.2.1. Creating a Data Store

An instance of a Cassandra 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("cassandra.contact.point", "");
parameters.put("cassandra.keyspace", "geomesa");
parameters.put("cassandra.catalog", "mycatalog");
org.geotools.data.DataStore dataStore =

16.2.2. Cassandra Data Store Parameters

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

Parameter Type Description
cassandra.catalog * String The name of the GeoMesa catalog table (previously geomesa.cassandra.catalog.table)
cassandra.contact.point * String The connection point for Cassandra, in the form <host>:<port> - for a default local installation this will be localhost:9042
cassandra.keyspace * String The Cassandra keyspace to use (must exist already)
cassandra.username String Cassandra user
cassandra.password String Cassandra password
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
