-----------------------------------------
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.
