[GitHub] [arrow-datafusion] e-dard commented on pull request #722: perf: improve performance of `SortPreservingMergeExec` operator

   Once DataFusion is using Arrow 5.0 (which @alamb informs me should be relatively soon), I will rebase this PR and get it green. 
   
   FWIW I have tested this PR internally and it has effectively eradicated `SortKeyCursor::compare` from our CPU profiles 🚀
