             Summary: Combining multiple 'in' criteria can prevent pushing criteria to database
                 Key: TEIID-2936
                 URL: https://issues.jboss.org/browse/TEIID-2936
             Project: Teiid
          Issue Type: Feature Request
    Affects Versions: 8.7
            Reporter: Mike Higgins
            Assignee: Steven Hawkins


When two 'in' criteria containing constant values on the same field are combined with an 'or', Teiid will combine the two into a single 'in' operation.

Since Oracle (for example)  has a 1000 item limit on the 'in' values, if the resulting combined list contains more than 1000 values, it can no longer be pushed down into Oracle for execution.
