             Summary: Enable loading state backend via configuration in state processor api
                 Key: FLINK-25423
                 URL: https://issues.apache.org/jira/browse/FLINK-25423
             Project: Flink
          Issue Type: Improvement
          Components: API / State Processor, Runtime / State Backends
            Reporter: Yun Tang
             Fix For: 1.15.0


Currently, state processor API would load savepoint via explictly initalizated state backend on client side, which is like {{StreamExecutionEnvironment#setStateBackend(stateBackend)}}:

{code:java}
Savepoint.load(bEnv, "hdfs://path/", new HashMapStateBackend());
{code}

As we all konw, stream env also support to load state backend via configuration to provide flexibility to load state backends especially some customized state backend. This could also benefit state processor API with similiar ability.
