> 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
