Class RetryDecision

A retry decision to adopt on a Cassandra exception (read/write timeout or unavailable exception).

There is three possible decision:

• Rethrow: no retry should be attempted and an exception should be thrown
• Retry: the operation will be retried. The consistency level of the retry should be specified.
• Ignore: no retry should be attempted and the exception should be ignored. In that case, the operation that triggered the Cassandra exception will return an empty result set.
