 To better accommodate scaling and performance needs, updating the `type` setting in `index_options` is possible with the [Update Mapping API](https://www.elastic.co/docs/api/doc/elasticsearch/operation/operation-indices-put-mapping), according to the following graph (jumps allowed):
 
 ```txt
-flat --> int8_flat --> int4_flat --> hnsw --> int8_hnsw --> int4_hnsw
+flat --> int8_flat --> int4_flat --> bbq_flat --> hnsw --> int8_hnsw --> int4_hnsw --> bbq_hnsw
 ```
 
-For updating all HNSW types (`hnsw`, `int8_hnsw`, `int4_hnsw`) the number of connections `m` must either stay the same or increase. For scalar quantized formats  (`int8_flat`, `int4_flat`, `int8_hnsw`, `int4_hnsw`) the `confidence_interval` must always be consistent (once defined, it cannot change).

 Updating `type` in `index_options` will fail in all other scenarios.
