memory

An in-memory, ETS-backed adapter for tests and examples — no database required. It evaluates queries directly against stored rows.

Supported: single-source all with where/order/limit/offset, aggregate selects (count/sum/avg/min/max), group_by with a projected aggregate select, FROM-subqueries and uncorrelated IN/EXISTS, insert (auto-incrementing integer id), update_all, delete_all, and transaction (snapshot/rollback). Upserts detect conflicts only for a Columns target (the store has no constraint catalog). Joins, HAVING, correlated subqueries, DISTINCT, window functions (expr.over), and CTEs (query.with_cte) are NOT evaluated here — those are exercised through the SQL renderer and the real Postgres adapter.
