 ### How does Flink support data analytics applications?
 
-Flink provides very good support for continuous streaming as well as batch analytics. Specifically, it features an ANSI-compliant SQL interface with unified semantics for batch and streaming queries. SQL queries compute the same result regardless whether they are run on a static data set of recorded events or on a real-time event stream. Rich support for user-defined functions ensures that custom code can be executed in SQL queries. If even more custom logic is required, Flink's DataStream API or DataSet API provide more low-level control. Moreover, Flink's Gelly library provides algorithms and building blocks for large-scale and high-performance graph analytics on batch data sets.

Review Comment:
   I think the [iteration](https://nightlies.apache.org/flink/flink-ml-docs-stable/docs/development/iteration/) capability supported in Flink ML can not be used to support typical graph processing capabilities (e.g. vertex-centric or gather-sum-apply). And there is currently no plan to support these graph processing capabilities in Flink ML.
   
   So it seems better not to add the paragraph suggested above.
