CStar

cstar intelligently parallelizes script execution based on Cassandra's ring and data center layout, preventing downtime during operations like upgrades, as emphasized in the README's comparison to generic tools.

Jobs can be halted and resumed using job IDs with output saved locally, ensuring no loss of progress during interruptions, a feature highlighted in the job management section.

Supports targeting via seed hosts, explicit lists, or host files, including multi-cluster operations, making it adaptable to various deployment scenarios without rigid constraints.

Scripts run nohuped on remote hosts, so they continue even if SSH connections drop, enhancing robustness for long-running maintenance tasks as described in the job execution details.
