------------------------------------

[~hequn8128] ok. we use stream non window join(this part of code we use Flink 
1.6.0 ) in actual production ,taskManger will OOM when there is a long 
expiration time。so ,we try to clean expired data by state ttl,so I think is a 
way to deal with too many timer on Heap.

[~fhueske] if use ttl , i think we dont need minRetentionTime and 
maxRetentionTime ,we just need config state update strategy.

> stream non window join support state ttl

> stream non window join function use timer to delete expired data,it is ok for 
> small amount of data or short expiration time,but it will be OOM(too many 
> timer)on taskManger  when there  is a long expiration time and  a large 
> amount of data。In fact, table module other state function has same problem,I 
> would like to contribute to fix it。
