------------------------------------------------------------------------
I believe that we should have formal docs on added syntax / types whatever. The
proper documentation about the whole ANN thing is something else. But
CQL.textile is basically the referential CQL document (or
doc/modules/cassandra/pages/developing/cql/cql_singlefile.adoc) and it should
be there.
I understand that there will be (hopefully) dedicated ANN documentation but
that is something else. Will we change CQL by merging this working? Yes, we
will ... so?

> Based off several mailing list threads (see "[POLL] Vector type for ML”,
> "[DISCUSS] New data type for vector search”, and "Adding vector search to SAI
> with heirarchical navigable small world graph index”), its desirable to add a
> new type “VECTOR” that has the following properties
> 1) fixed length array
> 2) elements may not be null
> 3) flatten array (aka multi-cell = false)
