@xuchuanyin What I have mentioned is that instead of adding the mapping in
datamap, handle while writing the datamap.
Currently the blocklet number is respective to each block while writing the
datamap , instead generate blocklet number respective to complete index file.
In this approach, we can eliminate the block to bloclet mapping completely
even inside datamaps. ---
