-Flink programs are regular programs that implement transformations on 
distributed collections
-(e.g., filtering, mapping, updating state, joining, grouping, defining 
windows, aggregating).
-Collections are initially created from sources (e.g., by reading from files, 
kafka topics, or from local, in-memory
-collections). Results are returned via sinks, which may for example write the 
data to
-(distributed) files, or to standard output (for example, the command line 
terminal).
-Flink programs run in a variety of contexts, standalone, or embedded in other 
programs.
-The execution can happen in a local JVM, or on clusters of many machines.
-
-Depending on the type of data sources, i.e. bounded or unbounded sources, you 
would either
-write a batch program or a streaming program where the DataSet API is used for 
batch
-and the DataStream API is used for streaming. This guide will introduce the 
basic concepts
-that are common to both APIs but please see our
-[Streaming Guide]({{ site.baseurl }}/dev/datastream_api.html) and
-[Batch Guide]({{ site.baseurl }}/dev/batch/index.html) for concrete 
information about
-writing programs with each API.
-
-**NOTE:** When showing actual examples of how the APIs can be used  we will use
-`StreamingExecutionEnvironment` and the `DataStream` API. The concepts are 
exactly the same
-in the `DataSet` API, just replace by `ExecutionEnvironment` and `DataSet`.

程序是实现了分布式集合转换(例如过滤、映射、更新状态、join、分组、定义窗口、聚合)的规范化程序。集合初始创建自数据源(例如读取文件、kafka 
主题,或本地内存中的集合)。结果通过 sink 返回,例如,它可以将数据写入(分布式)文件,或标准输出(例如命令行终端)。Flink 
程序可以在多种环境中运行,独立运行或嵌入到其他程序中。可以在本地 JVM 中执行,也可以在多台机器的集群上执行。
