**Other limitations include:**
-- Aggregate models are currently not supported.
- VARIANT columns can only create inverted indexes or bloom filter to speed up
query.
- Using the **RANDOM** mode or [group

- Non-standard JSON types such as date and decimal should ideally use static
types for better performance, since these types are infered to text type.
