StreamExecutionEnvironment.setStateBackend(org.apache.flink.runtime.state.StateBackend backend)
Deprecated.
The method is marked as deprecated because starting from Flink 1.19, the usage of
all complex Java objects related to configuration, including their getter and setter
methods, should be replaced by ConfigOption. In a future major version of Flink, this
method will be removed entirely. It is recommended to switch to using the ConfigOptions
provided for configuring state backend like the following code snippet:
|

Trigger<Object,GlobalWindow> |
GlobalWindows.getDefaultTrigger(StreamExecutionEnvironment env) |
Trigger<Object,TimeWindow> |
SlidingProcessingTimeWindows.getDefaultTrigger(StreamExecutionEnvironment env) |
abstract Trigger<T,W> |
WindowAssigner.getDefaultTrigger(StreamExecutionEnvironment env)
Deprecated.
the method is deprecated since Flink 1.19 because
StreamExecutionEnvironment is unused. Please use getDefaultTrigger and override
this method with an empty body instead. 1. If you override getDefaultTrigger(),
the getDefaultTrigger() will be invoked and the getDefaultTrigger(StreamExecutionEnvironment env) won't be invoked. 2. If you don't
override getDefaultTrigger(), the getDefaultTrigger(StreamExecutionEnvironment env) will be invoked in the default
implementation of the getDefaultTrigger(). |
