----------------------------------------------------
Summary: Add Optional Backoff on Retry to Cassandra Stress
Key: CASSANDRA-7821
URL: https://issues.apache.org/jira/browse/CASSANDRA-7821
Project: Cassandra
Issue Type: Improvement
Reporter: Russell Alexander Spitzer
Currently when stress is running against a cluster which occasionally has nodes
marked as down, it will almost immediately stop. This occurs because the retry
loop can execute extremely quickly if each execution terminates with a
{{com.datastax.driver.core.exceptions.NoHostAvailableException}} or
{{com.datastax.driver.core.exceptions.UnavailableException}}.
In case of these exceptions is will most likely be unable to succeed if the
retries are performed as fast as possible. To get around this, we could add an
optional delay on retries giving the cluster time to recover rather than
terminating the stress run.
We could make this configurable, with options such as:
* Constant # Delays the same amount after each retry
* Linear # Backoff a set amount * the trial number
* Exponential # Backoff set amount * 2 ^ trial number
This may also require adjusting the "thread is stuck check" to make sure that
the max retry timeout will not cause the thread to be terminated early.
