Delete rows from a table using a SQL predicate.

Delete rows from a table

Perform a merge-insert SQL query against a table. This can be used
to perform upserts. To perform an upsert, set `when_matched_update_all`
and `when_not_matched_insert_all` to true.


Merge-insert data to a table

Create an index on a column.

Vector index options are: `IVF_PQ` and `IVF_HNSW_SQ`. The `distance_type`
parameter is required for vector indices.

For [full text search](https://lancedb.github.io/lancedb/fts/), use `FTS`.
For [scalar indices](https://lancedb.github.io/lancedb/guides/scalar_index/),
use `BTREE`, `BITMAP`, or `LABEL_LIST`.
