.. _redis_config_props: Redis Data Store Configuration ============================== This section details Redis-specific configuration properties. For general properties, see :ref:`geomesa_site_xml`. geomesa.redis.age.off.interval ++++++++++++++++++++++++++++++ Sets how often features will be checked for expiration. The interval should be specified as a duration, for example ``1 hour`` or ``10 minutes``. By default, expiration will run every 10 minutes. See :ref:`redis_feature_expiry` for more details. geomesa.redis.tx.backoff ++++++++++++++++++++++++ Sets the back-off multiplier for retrying writes that fail due to concurrent conflicting clients. For each retry attempt, the client will wait based on ``geomesa.redis.tx.pause`` and this back-off multiplier. The multipliers are specified as a comma-delimited list of numbers, where each number corresponds to a retry attempt. For example, by default, the multipliers are ``1,1,2,2,5,10,20``, which means that the first and second retry attempts will use the pause unmodified, the third and fourth attempts will double the pause, the fifth and sixth attempts will multiply the pause by 5 and 10, respectively, and any subsequent attempts will multiply the pause by 20. There is also a small random delay added, to prevent clients from pausing for the exact same amount of time. See also ``geomesa.redis.tx.pause`` and ``geomesa.redis.tx.retry``. geomesa.redis.tx.pause ++++++++++++++++++++++ Sets the delay between retry attempts, for retrying writes that fail due to concurrent conflicting clients. For each retry attempt, the client will wait based on ``geomesa.redis.tx.backoff`` and this pause value. The pause value should be specified as a duration, and defaults to ``100ms``. See also ``geomesa.redis.tx.backoff`` and ``geomesa.redis.tx.retry``. geomesa.redis.tx.retry ++++++++++++++++++++++ Sets the number of times to attempt to write to Redis for a given transaction. Due to multi-threading, some writes to Redis may fail if clients are simultaneously updating the same schema. In such a scenario, the writes will be retried several times, with increasing back-off times to allow for a busy system. By default, writes are retried ``10`` times. See also ``geomesa.redis.tx.backoff`` and ``geomesa.redis.tx.pause``. geomesa.redis.write.batch +++++++++++++++++++++++++ Sets the default batch size for writing features to Redis. When using a GeoTools, ``FeatureWriter``, data will only be sent to Redis once the batch size is reached (or with an explicit ``flush`` or ``close`` of the writer). By default, the batch size is set to ``1000`` features.
