Ted Yu commented on HBASE-14921: -------------------------------- bq. We flatten the index, thereby reducing the metadata memory overhead. Can you explain in bit more detail on the savings ? bq. Arrange flattening also to CellChunkMap, currently impossible to get the chunk ID out of already created cell metadata What's plan for flattening to CellChunkMap w.r.t. getting the chunk Id ?
