Zhuoyue Huang updated HBASE-25364:
----------------------------------
Description:
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
