Michael Semb Wever commented on CASSANDRA-18504:
------------------------------------------------
bq. if this was a "just in case" then maybe scrub is the best option for 5.0
upgrade?
I think we should floor 5.0 compatibility to `minimum_version=me`, encouraging
users to have addressed this problem before the upgrade. (And that you need to
use tools from 3.x or 4.x, and any scrub from <me to >=me always perform the
header check.)
> 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)
