Michael Semb Wever commented on CASSANDRA-18504:
------------------------------------------------
The above comment lead to (the opposite action, in restoring compatibility)
CASSANDRA-20394. But a problem we face here is we can no longer reproduce any
situation where the header fix is actually needed. SSTables from 3.0.x that we
know are written with the wrong headers are loading fine into 3.11 (3.11.5 and
3.11.latest tested). So let's leave that ticket open, if something hits it
then we can apply it.

> 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

> 2) elements may not be null
> 3) flatten array (aka multi-cell = false)
