I see couple failures which seem to be related:

That was on trunk branch but 5.0 branch has same failures.
This seems to be a different issue from VectorDistributedTest and
rangeRestrictedTest ?

> Add support for vector search in SAI
> ------------------------------------
>
> Key: CASSANDRA-18715
> URL: https://issues.apache.org/jira/browse/CASSANDRA-18715
> Project: Cassandra
> Issue Type: Improvement
> Components: Feature/Vector Search
> Reporter: Mike Adamson
> Assignee: Mike Adamson
> Priority: Normal
> Fix For: 5.0-alpha2, 5.0, 5.1
>
> Time Spent: 25.5h
> Remaining Estimate: 0h
>
> The patch associated with this ticket adds a new vector index to SAI. This
> introduces the following new elements and changes to SAI:
> * VectorMemtableIndex - the in-memory representation of the vector indexes
> that writes data to a DiskANN instance
> * VectorSegmentBuilder - that writes a DiskANN graph to the following
> on-disk components:
> ** VECTOR - contains the floating point vectors associated with the graph
> ** TERMS - contains the HNSW graph on-disk representation written by a
> HnswGraphWriter
> ** POSTINGS - contains the index postings as written by a
> VectorPostingsWriter
> * VectorIndexSegmentSearcher - used to search the on-disk DiskANN graph
