John Russell created IMPALA-5371:
------------------------------------

             Summary: Document TIMESTAMP support for Kudu tables
                 Key: IMPALA-5371
                 URL: https://issues.apache.org/jira/browse/IMPALA-5371
             Project: IMPALA
          Issue Type: Task
          Components: Docs
    Affects Versions: Impala 2.9.0
            Reporter: John Russell
            Assignee: John Russell
             Fix For: Impala 2.9.0


New functionality from IMPALA-5137.

"No TIMESTAMP" restriction to be lifted in several places.

Some changes to precision to document under TIMESTAMP page. (A query won't get back exactly the same value that gets inserted into a Kudu table.)

Possible performance caveat if there's significant overhead converting on the way in and out.

Don't think much impact on using date/time functions on TIMESTAMP from Kudu tables. Possibly some nuances related to rounding and extraction functions.
