+excerpt: Flink has implemented the sort-based blocking shuffle (FLIP-148) for
batch data processing. In this blog post, we will take a close look at the
design & implementation details and see what we can gain from it.
+---
+
+The part one of this blog post will explain the
[motivation](#why-did-we-introduce-the-sort-based-implementation) behind
sort-based blocking shuffle, and present the [benchmark
results](#benchmark-results) to show how you can benefit from the new blocking
shuffle implementation. The [operations & performance
tuning](#operations--tuning) section provides guidelines on how to use this new
feature.
