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 ?

Thanks
