Bedrock.ControlPlane.Director.Recovery.PersistencePhase (bedrock v0.6.0)

View Source

Persists cluster configuration through a complete system transaction.

Constructs a system transaction containing the full cluster configuration and submits it through the entire data plane pipeline. This simultaneously persists the new configuration and validates that all transaction components work correctly.

Stores configuration in both monolithic and decomposed formats. Monolithic keys support coordinator handoff while decomposed keys allow targeted component access.

If the system transaction fails, the director exits immediately rather than retrying. System transaction failure indicates fundamental problems that require coordinator restart with a new epoch.

Transitions to monitoring on success or exits the director on failure.
