> Redo the getMidPoint() in HFileWriterImpl to get rid of the double comparison
> process
> -------------------------------------------------------------------------------------
>
> Key: HBASE-25364
> URL: https://issues.apache.org/jira/browse/HBASE-25364
> Project: HBase
> Issue Type: Improvement
> Reporter: Zhuoyue Huang
> Assignee: Zhuoyue Huang
> Priority: Minor
> Fix For: 3.0.0-alpha-1, 2.5.0
>
>
> There is a TODO like this "TODO: Redo so only a single pass over the arrays
> rather than one to compare and then a second composing midpoint." in
> getMidpoint() of class HFileWriteImpl
>
> The old logic compares the left byte array and the right byte array twice：
> # A comparison is performed before composing MinimumMidpointArray
> # During composing of MinimumMidpointArray, bytes were comparing again
>
> My optimization combines them into one
