Andres de la Peña commented on CASSANDRA-18715:
-----------------------------------------------
The runs have finished. 5.0 is perfectly clean. {{trunk}} however shows
failures for:
* {{VectorDistributedTest.rangeRestrictedTest}}
* {{VectorDistributedTest.testPartitionRestrictedVectorSearch}}
* {{CQLVectorTest.sandwichBetweenUDTs}}
* {{VectorSegmentationTest.testMultipleSegmentsForCompaction}}
I think the only known one was
{{{}VectorDistributedTest.rangeRestrictedTest{}}}. The others are well below 1%
flakiness.
[~mike_tr_adamson] is it ok to commit the current fix for
{{VectorUpdateDeleteTest}} and deal with the others on a separate ticket?

> 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
