using-embedded-database
Use when running **SQLite or DuckDB inside an application process** as the durable store — not as a development convenience but as the production database. Use when scaling an SQLite layer that worked at low concurrency and is now hitting SQLITE_BUSY, WAL bloat, lock contention, schema-migration ceremony, or correctness gaps under multi-process writers. Use when introducing DuckDB as an OLAP complement to an OLTP SQLite store, or when picking between the two for a new component. Pairs with `/web-backend` (the API surface above the DB) and `/audit-pipelines` (when the DB is also the audit trail). Do not load for server databases (Postgres, MySQL), key-value stores, or ORM choice in isolation.
