Monitoring Cassandra cluster health

You can secure the good health of a Cassandra cluster by monitoring the node status in Pega Platform and by running regular repair operations. Regular cluster maintenance is important for Cassandra clusters that manage data with a specified time-to-live (TTL) expiration period. After data exceeds the TTL period, the Cassandra cluster marks the data with a tombstone. By running repair processes, you automatically remove the tombstone data.
