向你展示了如何使用 Flink 编写流数据应用程序。你可以从中学习到 Flink
应用程序的故障恢复、升级、并行度提高、并行度降低和程序运行状态的指标监控等特性。
Review comment:
`并行度提高、并行度降低` 如果改成 `修改并行度` 会好一些吗？

step-by-step introduction to

a small skeleton
-project, and then shows how to extend it to a simple application.

- to implement a simple DataStream application and how to extend it to be
stateful and use timers.
- The DataStream API is Flink's main abstraction for implementing stateful
streaming applications

+**代码练习**是快速入门的最佳方式，通过代码练习可以逐步深入地理解 Flink API。每个示例都演示了如何构建基础的 Flink
代码框架，并如何逐步将其扩展为简单的应用程序。
-* Flink's **Table API** is a relational API used for writing SQL-like queries
in Java, Scala, or
- Python, which are then automatically optimized, and can be executed on batch
or streaming data
- with identical syntax and semantics. The [Table API code walkthrough for
Java and Scala]({% link
- getting-started/walkthroughs/table_api.md %}) shows how to implement a
simple Table API query on a
- batch source and how to evolve it into a continuous query on a streaming
source. There's also a
- similar [code walkthrough for the Python Table API]({% link
- getting-started/walkthroughs/python_table_api.md %}).
+* [**DataStream API 示例**]({% link
getting-started/walkthroughs/datastream_api.zh.md %}) 展示了如何实现一个基本的 DataStream
应用程序，并把它扩展成有状态的应用程序。DataStream API 是 Flink 的主要抽象，可用于在 Java/Scala
语言中实现具有复杂时间语义的有状态数据流处理的应用程序。

`可用于在 Java/Scala 语言中` 是否可以改成 `可用于 Java/Scala 中` 呢
