Python RuntimeContext.get_state Examples

Example #1

 def open(self, runtime_context: RuntimeContext):
     state_descriptor = ValueStateDescriptor("state", Types.FLOAT())
     state_ttl_config = StateTtlConfig \
         .new_builder(Time.seconds(1)) \
         .set_update_type(StateTtlConfig.UpdateType.OnReadAndWrite) \
         .disable_cleanup_in_background() \
         .build()
     state_descriptor.enable_time_to_live(state_ttl_config)
     self.state = runtime_context.get_state(state_descriptor)
