@xuchuanyin what is the issue you are actually facing? Blocklet ids here
are only virtual and count as per the number of blocklets present in the
indexfile. If the issue is with other datamaps like lucene then better correct
the blocklet order as per the indexfile while writing the datamap. It also
saves memory and simplifies the datamap writing by avoiding block name.
Maintaining block names here is not memory efficient.
