Mike Adamson updated CASSANDRA-18715:
-------------------------------------
Description:
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
