SQL And PartiQL - CefasDB Docs
CefasDB SQL supports partition queries, filters, conditional writes, ANN ordering, and EXPLAIN.
Documentation excerpt
CefasDB includes a SQL parser, planner, and executor for operational queries. It is not intended to be a full relational database. It is a pragmatic query surface over the item model and index system.
SELECT INSERT UPDATE DELETE RETURNING on supported mutations PartiQL-style execution through execute-statement
Predicates can include key conditions, scalar comparisons, boolean composition, and supported functions.
The CLI update path can be translated into CefasDB SQL update behavior. This keeps compatibility with expression-based mutation scripts while letting the engine use one mutation path internally.
