> 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.
