-Apache Flink streaming applications are typically designed to run indefinitely
or for long periods of time.
-As with all long-running services, the applications need to be updated to
adapt to changing requirements.
-This goes the same for data schemas that the applications work against; they
evolve along with the application.
+Apache Flink 流应用通常被设计为永远或者长时间运行。
+与所有长期运行的服务一样，需要更新应用程序以适应不断变化的需求。
+对于应用程序处理的数据结构来说，这是相同的；它们也随应用程序一起升级。
-This page provides an overview of how you can evolve your state type's data
schema.
-The current restrictions varies across different types and state structures
(`ValueState`, `ListState`, etc.).
+此页面概述了如何升级状态类型的数据结构。
+目前的限制因不同类型和状态结构而异（`ValueState`、`ListState` 等）。
