zero-downtime-database-migration-expand-contract.txt

Act as a Senior Database Reliability Engineer (DBRE). Develop a foolproof, step-by-step technical execution plan for a Zero-Downtime database migration utilizing the 'Expand and Contract' pattern on a massive [DATABASE_ENGINE] cluster. To execute the highly destructive [SCHEMA_ALTERATION] on the heavily trafficked [TABLE_NAME], you must detail the 4 strict phases: 1) Expand (add the new column without locking), 2) Migrate (deploy code to dual-write to both columns), 3) Backfill (run a batch script to migrate legacy rows), and 4) Contract (drop the old column). Provide the exact SQL statements required to avoid table-level locks.
