Gemini CLIAbout this skill
Relational databases (Postgres, MySQL) — ACID, SQL, joins, isolation levels, MVCC vs locking, indexes, JSONB, HA topologies. Reach for this when you see lost updates, phantom reads, double-billed customers, "duplicate charges" after a retry, deadlocks under load, p99 query spikes from missing indexes, replication lag breaking read-your-writes, foreign-key cascading failures, or someone reaching for Mongo/DynamoDB to avoid "writing SQL" when they actually need transactions.
