Patch Set 2: Code-Review+1 (2 comments) +2 for backend and tests http://gerrit.cloudera.org:8080/#/c/6038/2/be/src/exprs/aggregate-functions-ir.cc File be/src/exprs/aggregate-functions-ir.cc: Line 447: // The scale of the accumulated sum is set to the scale of the output type. I think this comment would be better in the frontend code since that's where the compatibility needs to be maintained. http://gerrit.cloudera.org:8080/#/c/6038/2/testdata/workloads/functional-query/queries/QueryTest/decimal-exprs.test File testdata/workloads/functional-query/queries/QueryTest/decimal-exprs.test: PS2, Line 197: 0 do these results make sense? seems surprising that this decimal place is always 0, but i haven't looked at the data. -- To view, visit http://gerrit.cloudera.org:8080/6038 To unsubscribe, visit http://gerrit.cloudera.org:8080/settings Gerrit-MessageType: comment Gerrit-Change-Id: I28f5ef0370938440eb5b1c6d29b2f24e6f88499f Gerrit-PatchSet: 2 Gerrit-Project: Impala-ASF Gerrit-Branch: master Gerrit-Owner: Michael Ho <[email protected]> Gerrit-Reviewer: Dan Hecht <[email protected]> Gerrit-Reviewer: Michael Ho <[email protected]> Gerrit-HasComments: Yes
