------------------------------------

             Summary: Consider eliminating threadlocals from MVCC code
                 Key: HBASE-9754
                 URL: https://issues.apache.org/jira/browse/HBASE-9754
             Project: HBase
          Issue Type: Bug
            Reporter: Lars Hofhansl


Brought up by [~vrodionov] and [~yuzhihong@gmail.com].
Currently we use ThreadLocals to communicate the current readpoint between a RegionScanner
and the Store{File}Scanner's down the stack.
Since ThreadLocals are not cheap we should consider whether it is possible to pass the readpoint
through the call stack instead.
