 # Apache Uniffle (Incubating)
 
-Uniffle is a unified remote shuffle service for distributed compute engines.
-It provides the ability to aggregate and store shuffle data on remote servers,
-thus improving the performance and reliability of large jobs.
-Currently it supports [Apache Spark](https://spark.apache.org) and [Apache 
Hadoop MapReduce](https://hadoop.apache.org).
+Uniffle is a high performance, general purpose remote shuffle service for 
distributed computing engines.
+It provides the ability to push shuffle data into centralized storage service,
+changing the shuffle style from "local file pull-like style" to "remote block 
push-like style".
+It brings in several advantages like supporting disaggregated storage 
deployment,
+super large shuffle jobs, and high elasticity.
+Currently it supports [Apache Spark][1] and [Apache Hadoop MapReduce][2].
