Anoop Sam John commented on HBASE-16143:
----------------------------------------
bq.list.add(pos, getActive().getSegmentScanner(readPt, order+1));
Why use pos based add? It is ArrayList we know so we will get insert order. It
is fine to just call add(<element>)
Where do u use MemstoreScanner now? Previous it was returning one
MemstoreScanner to the StoreScannr layer.Now it is N KVScanners? Intended
change?
> Change MemstoreScanner constructor to accept List<KeyValueScanner>

> 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.
