> A minor change that helps in creating a memstore that avoids the compaction process and
just allows to creates a pipeline of segments and on flush directly reads the segments in
the pipeline and flushes it out after creating a snapshot of the pipeline. Based on test results
and updated patch on HBASE-14921 (to be provided) will see how much flattening helps us.
