[SYSTEM] Active incident: Dual-Write Inconsistency During Database Migration
[SYSTEM] Type "help" for a list of investigation commands.

Execute Remediation⚠ PROD
You're migrating from MySQL to Cassandra. During the dual-write phase, writes are sent to both MySQL and Cassandra. A Cassandra network partition caused 2 hours of write failures — all writes during this period went only to MySQL. The migration team didn't detect this. Now, Cassandra is missing 2 hours of data. If you cut over to Cassandra, users will see missing records. You cannot afford extended downtime for a full re-sync.
