Stefan Miklosovic commented on CASSANDRA-18715:
-----------------------------------------------
Thank you [~mike_tr_adamson] for the fast fix.
+1 on that particular patch you just posted.
Do we want to wait for another one too so it might be committed all at once and
we are done or do you prefer to merge it one by one? (VectorDistributedTest /
rangeRestrictedTest)

> 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
