[jira] [Created] (IMPALA-7090) EqualityDisjunctsToInRule should respect the limit on the number of children in an expr

Tianyi Wang created IMPALA-7090:
-----------------------------------

             Summary: EqualityDisjunctsToInRule should respect the limit on the number of children in an expr
                 Key: IMPALA-7090
                 URL: https://issues.apache.org/jira/browse/IMPALA-7090
             Project: IMPALA
          Issue Type: Bug
    Affects Versions: Impala 2.12.0, Impala 3.0
            Reporter: Tianyi Wang
            Assignee: Tianyi Wang


Currently EqualityDisjunctsToInRule introduced in IMPALA-5280 might create an expr with unlimited number of children and fails a query, which should be avoided. The easy solution is to not apply the rewrite when the number of children is large.
