Re: Reading Flink states from svaepoint uning State Processor API
Hi Min, The only requirement is that your state descriptors be configured identically as those used in your datastream API. So if you registered custom TypeInformation / serializer in your streaming job you will need those here as well. I would also look at the ExecutionConfig on your DataStream app as that can dictate how your serializers are configured.

Re: Reading Flink states from svaepoint uning State Processor API
Hi Min, Usually, you should be able to provide type information and thereby a serializer via the StateDescriptors which you create to access the state. If this is not working, then you need to give us a bit more context to understand what's not working. I am also pulling in Seth who is the original author of the state processor API.

Reading Flink states from svaepoint uning State Processor API
Hi, I am using Flink 1.10.1 and try to read the flink states from a savepoint using Flink state processor API. It works well when state types are the normal Java type or Java POJOs. When Avro generated Java classes are used as the state type, it does not read any states anymore. Are any additional customer serializers required in this situation?
