Database Migration Reviews With AI: Catching the Lock You Didn't See
Schema migrations are where production outages hide. AI can review migrations against known-bad patterns — exclusive locks on big tables, irreversible changes, distributed-system race conditions.

Section 1
The premise
Migration safety lives in the corners (lock behavior, replica timing, online-schema-change tools); AI can scan for known-bad patterns.
What AI does well here
- Identify lock-acquiring statements on tables larger than threshold
- Flag migrations that block reads or writes during execution
- Surface non-reversible changes that need backfill before being safe
- Recommend safer alternatives (online schema change tools, multi-step migrations)
What AI cannot do
- Substitute for testing in a production-shape environment
- Catch every database-engine-specific edge case
- Replace the senior database engineer's review for high-stakes changes

Agents vs. Autocomplete — the Mental Model Shift
Autocomplete is a suggestion. An agent is an actor. The mental model you bring to each is different, and conflating them is the number-one reason teams trip over AI coding.
