             Summary: Make resumable bootstrap feature optional
                 Key: CASSANDRA-17679
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-17679
             Project: Cassandra
          Issue Type: New Feature
          Components: Consistency/Streaming
            Reporter: Josh McKenzie
            Assignee: Josh McKenzie


From the patch I'm working on:

{code}
# In certain environments, operators may want to disable resumable bootstrap in order to avoid potential correctness
# violations or data loss scenarios. Largely this centers around nodes going down during bootstrap, tombstones being
# written, and potential races with repair. By default we leave this on as it's been enabled for quite some time,
# however the option to disable it is more palatable now that we have zero copy streaming as that greatly accelerates
# bootstraps. This defaults to true.
# resumable_bootstrap_enabled: true
{code}

Not really a great fit for guardrails as it's less a "feature to be toggled on and off" and more a subset of a specific feature that in certain circumstances can lead to issues.
