Andres de la Peña commented on CASSANDRA-18715:
-----------------------------------------------
It seems this was committed over the weekend without a final CI round including
the last commit added on Thursday. That commit included the test that we have
seen failing on Jenkins. It also included a few new unit tests that we have not
run in the multiplexer.
Here are runs for all the tests with both j11 and j17, including the last fix:

> 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
