Using the Redis Data Store Programmatically =========================================== Creating a Data Store --------------------- An instance of a Redis data store can be obtained through the normal GeoTools discovery methods, assuming that the GeoMesa code is on the classpath. .. code-block:: java Map parameters = new HashMap<>(); parameters.put("redis.url", "redis://localhost:6379"); parameters.put("redis.catalog", "geomesa"); org.geotools.data.DataStore dataStore = org.geotools.data.DataStoreFinder.getDataStore(parameters); .. _redis_parameters: Redis Data Store Parameters --------------------------- The data store takes several parameters (required parameters are marked with ``*``): ====================================== ======= ==================================================================================== Parameter Type Description ====================================== ======= ==================================================================================== ``redis.url *`` String Redis connection URL. The URL can be used to specify the Redis database and credentials, if required - for example, 'redis://user:pass@host:port/db' ``redis.catalog *`` String The name of the GeoMesa catalog table. In Redis, this is the base key used for inserts ``redis.connection.pool.size`` Integer Max number of simultaneous connections to use ``redis.connection.pool.validate`` Boolean Test connections when borrowed from the pool. Connections may be closed due to inactivity, which would cause a transient error if validation is disabled ``redis.pipeline.enabled`` Boolean Enable pipelining of query requests. This reduces network latency, but restricts queries to a single execution thread ``geomesa.query.threads`` Integer The number of threads to use per query (if not pipelining) ``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.stats.generate`` Boolean Toggle collection of statistics for newly created feature types ``geomesa.query.audit`` Boolean Audit queries being run. Queries will be written to a log file ``geomesa.query.loose-bounding-box`` Boolean Use loose bounding boxes - queries will be faster but may return extraneous results ``geomesa.query.caching`` Boolean Toggle caching of results ``geomesa.security.auths`` String Comma-delimited superset of authorizations that will be used for queries ``geomesa.security.force-empty-auths`` Boolean Forces authorizations to be empty ====================================== ======= ==================================================================================== More information on using GeoTools can be found in the `GeoTools user guide `__.
