@zentol Thanks, I think it's the wrong place to ask But Actually We have 
tried to use AvroTypeInfo, But it was unable to restore from the savepoint 
(Note we have changed the schema and class with 1 extra variable) So why I was 
asking if I can get a very minimal example or hint to check Am I am doing 
something wrong? I am using Scala.

@StephanEwen Are these changes part of 1.5 or 1.4, Do you have any example 
how I can use this with states and CEP? Please give me some hint. I have seen 
test cases of Input and Output only. State evolution is the main issue for us 
nowadays.

I think I have to wait for 1.4 cause there are a lot of changes in other 
files too between 1.3.2 release and this commit.

Yeah, But I think 1.4 will take some more couple of weeks. As unable to 
restore the state, So it's necessary to change for me.

While applying the patch it's giving a lot of conflicts. I think due to 
changes in between. So why I had doubts. I'll apply these changes manually.

Can I directly use these changes in the release-1.3.2 tag or there in 
between dependencies?

Again getting this error. After changing state backend from Rocksdb it's 
working fine.
