Sihua Zhou updated FLINK-9474:
------------------------------
    Description: We can implement an approximate version of "distinct filter" 
base on the "Elastic Bloom Filter", It could be very fast because we don't need 
to query the state anymore, its accuracy should could be configurable. e.g 95%, 
98% and it might unable to support retraction.  (was: We can implement an 
approximate version of "count distinct" base on the "Elastic Bloom Filter", It
