Andres de la Peña commented on CASSANDRA-18504:
-----------------------------------------------
[~smiklosovic] There is a dedicated ticket for adding ANN search docs,
CASSANDRA-18604. I guess the doc for the new vector type can be added during
that ticket, since the data type is closely related to its index. Or, if we
want to add it to {{CQL.textile}} during this ticket, I can help with it.
[~dcapwell] I have opened CASSANDRA-18613 for UDF support. It's almost patch
available but I still have to finish some things for types with variable length.

> 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)
