stack commented on HBASE-15082:
-------------------------------
bq. could we port the sibling issue to branch-1.2?
The write pipeline changed a load with HBASE-12751. Porting the 'hack' from
branch-1.1 is mostly done as part of this attached patch. I could spend time
distilling and testing just forward porting the 'hack' for a 1.2. Preferred
trying to do the proper 'fix' given HBASE-12751 opens up new vistas allowing
reordering of when edits are sync'd and when they can go to memstore.
> Fix merge of MVCC and SequenceID performance regression
