Data stores

Data stores Beyond the SQL dialects, prorm ships adapters for 88 non-relational stores — documents, key-value, wide-column, graph, vector, search, object storage, queues and more. These are not dialects A SQL dialect implements a shared contract: give it a FindOptions and it returns SQL. These stores do not share one, and pretending they did would be a lie — a document store, a blob bucket and a message queue have nothing meaningful in common at the query level. So each store implements only NoSqlStore, the minimal connection lifecycle (connect, disconnect, isConnected, getClient), and then exposes its own API shape on top. MongoStore gives you filters and aggregation pipelines; RedisStore gives you commands and TTLs; S3Store gives you object operations. There are no models, no define(), no DDL and no joins. getClient() always returns the underlying driver, so anything an adapter does not wrap is still reachable. Drivers are peer dependencies Adapters lazy-load their driver, so installing prorm does not pull in 88 database clients. Install the one you need — mongodb, ioredis, @elastic/elasticsearch and so on — alongside it. 88 stores, grouped by what they are for. The catalogue Document Schema-flexible JSON-ish documents, queried by filter rather than by join.
