> Tool to offline-dump the cluster metadata from an instance
> ----------------------------------------------------------
>
> Key: CASSANDRA-21129
> URL: https://issues.apache.org/jira/browse/CASSANDRA-21129
> Project: Apache Cassandra
> Issue Type: New Feature
> Components: Transactional Cluster Metadata
> Reporter: Abhijeet Dubey
> Assignee: Abhijeet Dubey
> Priority: Normal
> Attachments: text-output.txt, to-string-dump-output.txt
>
> Time Spent: 10m
> Remaining Estimate: 0h
>
> When a Cassandra node fails to start due to Transactional Cluster Metadata
> (TCM/CEP-21) corruption or issues, operators need a way to inspect the
> cluster metadata state offline without starting the node. The existing tools
> (nodetool, cqlsh) require a running node, leaving operators blind when
> debugging startup failures.
>
> When a node fails to start due to TCM corruption or inconsistencies,
> operators have no way to inspect the metadata state without a running node.
> This tool fills that gap by reading directly from SSTables.
