[jira] [Created] (KUDU-1446) Consider data types in predicate evaluation order

Todd Lipcon created KUDU-1446:
---------------------------------

             Summary: Consider data types in predicate evaluation order
                 Key: KUDU-1446
                 URL: https://issues.apache.org/jira/browse/KUDU-1446
             Project: Kudu
          Issue Type: Improvement
          Components: perf
    Affects Versions: 0.8.0
            Reporter: Todd Lipcon
            Priority: Minor


Currently, we determine what order to apply predicates only based on the type of comparison (equality vs range). Within a category, we should also use the data type -- evaluating predicates on smaller columns is more efficient so should be preferably done first.
