[jira] [Created] (IMPALA-9294) CLONE - Support DECIMAL for min-max runtime filters

Vladimir Verjovkin created IMPALA-9294:
------------------------------------------

             Summary: CLONE - Support DECIMAL for min-max runtime filters
                 Key: IMPALA-9294
                 URL: https://issues.apache.org/jira/browse/IMPALA-9294
             Project: IMPALA
          Issue Type: Improvement
          Components: Backend
    Affects Versions: Impala 2.12.0
            Reporter: Vladimir Verjovkin
            Assignee: Janaki Lahorani
             Fix For: Impala 3.2.0


Since min-max runtime filters are only supported for Kudu, and since at the time they were implemented Kudu didn't support DECIMAL, we didn't implement DECIMAL min-max runtime filters.

There's ongoing work to add support for DECIMAL on Kudu (IMPALA-5752). To start, min-max runtime filters will just be disabled for DECIMAL targets, but we should extend MinMaxFilter to support it.
