David Capwell commented on CASSANDRA-18504:
-------------------------------------------
spoke with [~adelapena] and we are going to block vectors from being reachable
from UDFs for now, and once client work is ready we can look to add; that way
no breaking changes happen...
We may also want to relook at this layer, as its very easy for new types to not
know about this... I only got lucky that someone asked how they add to this
class without breaking things (good timing)... Either have AbstractType return
a DataType, or rethink things... this layer "mimics" client, but actually isn't
client (different package)...
> Added support for type VECTOR<type, dimension>

> 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)
