replicationStrategy

Default Value: NetworkTopologyStrategy
Valid Values: SimpleStrategy, NetworkTopologyStrategy
Changes Take Effect: After start or restart

Replication strategy name, as described at http://docs.datastax.com/en/cassandra/2.0/cassandra/architecture/architectureDataDistributeReplication_c.html.

Warning

Genesys strongly recomends not using SimpleStrategy. If you use SimpleStrategy, you cannot use more than one data center and KeySpaces you create will be difficult to migrate to NetworkTopologyStrategy once they contain a lot of data. Also see https://docs.datastax.com/en/cassandra/2.0/cassandra/architecture/architectureDataDistributeReplication_c.html

If you set your replication strategy to SimpleStrategy you must also:

Configure a replication factor in the replicationStrategyParams option.
For embedded Cassandra, set the endpointSnitch option of the [cassandraEmbedded] section to SimpleSnitch.
For external Cassandra, set endpoint_snitch: SimpleSnitch in your cassandra.yaml file.

replicationStrategyParams

Default Value: 'OperationalDC':1
Valid Values: See the Cassandra replication configuration
Changes Take Effect: After start or restart

A comma-separated list of replication strategy parameters, where every list item is a colon-separated pair whose first item is the data center name enclosed in single quotes and whose second item is the number of replicas for that data center. For example, 'OperationalDC1': 3, 'OperationalDC2': 2 indicates that the OperationalDC1 data center includes 3 data replicas, while OperationDC2 includes 2 data replicas. For more information, consult http://docs.datastax.com/en/cassandra/2.0/cassandra/architecture/architectureDataDistributeReplication_c.html.

retention.entity.all

Default Value: 0 seconds (8.5.1 and later); 15 (8.5.0)
Valid Values: String (8.5.1); Integer (8.5.0)
Changes Take Effect: After start or restart
Modified: 8.5.1

Starting with version 8.5.1, this value (as a string) specifies the time to live (TTL) for all entities in the Cassandra database, in the n time-unit format. For example, 1 second.

In version 8.5.0, this value (as an integer) specifies the time to live (TTL) for all entities in the Cassandra database, in the time units set in the retention.time-unit option.

This option affects all business entities in the database.

retention.entity.<object>

Default Value: 0 seconds (8.5.1); none (8.5.0)
Valid Values: string (8.5.1); integer (8.5.0)
Changes Take Effect: After start or restart
Modified: 8.5.1

As of version 8.5.1, this value (as a string) specifies the time-to-live (TTL) for specific business entities in the Cassandra database, in the format "n time-unit". For example, 1 day. This option only affects the business entity specified by <object>.

In version 8.5.0, this value (as an integer) specifies the time-to-live (TTL) for the selected entity, in the time units set in the options. <object> must be replaced with a business entity name.
