Tensor Query Language (TQL)
A high-performance, SQL-like query engine (implemented in C++ inside Deep Lake) for filtering datasets and running hybrid embedding-plus-attribute search. TQL queries are executed through the SDK via `ds.query()` or `vector_store.search(query=)`, and require an authenticated Activeloop account (not available on purely local datasets). This is a query language surfaced through the SDK, not a standalone REST API.
