Cassandra IN query not working if table has SET type column

Question

I am new to Cassandra. I got a issue in CQL IN query ,if table has SET type column it works.

CREATE TABLE test (
    test_date bigint, 
    test_id

I'm not sure why this restriction should apply particulary for collections. But in your case you can get around this issue by making the test_id part of your partition key:

PRIMARY KEY((test_date,test_id))

This will allow you to do IN queries as long as you specify the first part of the composite key (test_date).
