Reaper for Apache Cassandra can be used with either an ephemeral memory storage or persistent database. For persistent scalable database storage, a Cassandra cluster can be set up to back Reaper. To use a Cassandra cluster as the backed storage for Reaper set storageType to a value of cassandra in the Reaper configuration file.
Further information on the available storage options is provided in the following section.
Cassandra Sample YAML files are available in the src/packaging/resource directory for each of the above storage options:
cassandra-reaper-memory.yaml
cassandra-reaper-cassandra.yaml
For configuring other aspects of the service, see the available configuration options in the Configuration Reference.
The Cassandra storage is most useful in cases where multiple Reaper instances are running against the same cluster. The database will be used as a coordination layer between instances. The Local storage can only be used when a single Reaper instance is running against the cluster(s).
