filter cardinality estimation #190

Open patelprateek opened 1 year ago

patelprateek commented 1 year ago

For large scale data the query filters can take long time to execute and return data . the returned data can also be large like millions of documents . Is there any functionality to be able to get some quick approximate estimate for query filters that can be potentially used to decide whether to run the query or not. If not , would like to know any recommendation or ideas on how we can implement or build that functionality ?
