 # State Backends
+# State Backends 状态后端
 
 Flink provides different state backends that specify how and where state is stored.
+Flink提供不同的状态后端，指定如何和在何处存储状态。
 
 State can be located on Java’s heap or off-heap. Depending on your state backend, Flink can also manage the state for the application, meaning Flink deals with the memory management (possibly spilling to disk if necessary) to allow applications to hold very large state. By default, the configuration file _flink-conf.yaml_ determines the state backend for all Flink jobs.
+状态可以位于Java的堆或堆上。根据您的状态后端，FLink还可以管理应用程序的状态，这意味着FLink处理内存管理（如果需要，可能会溢出到磁盘），以允许应用程序保持非常大的状态。默认情况下，配置文件_flink-constyaml_确定所有flink作业的状态后端。
 
 However, the default state backend can be overridden on a per-job basis, as shown below.
+但是，可以在每个作业的基础上重写默认状态后端，如下所示。
