ramkrishna.s.vasudevan commented on HBASE-14921:
------------------------------------------------
bq.We can do it when we have like e.g. 10 segments in the pipeline. If we are
going to simply flush it all to disk we are going to create many small files
and their compaction is going to run on disk then...
[~anastas] - The idea was to flush all the segments into one file. So the
snapshot will contain 10 segments and all the 10 will be flushed at one shot.
Not that we will create 10 files - 1 out of each segment.
I am just reviewing this code. If the patch is not updated in RB can you update
it?
