Change subject: IMPALA-9633: Implement ds_hll_union() ...................................................................... Patch Set 4: (2 comments) http://gerrit.cloudera.org:8080/#/c/16095/4/be/src/exprs/aggregate-functions-ir.cc File be/src/exprs/aggregate-functions-ir.cc: http://gerrit.cloudera.org:8080/#/c/16095/4/be/src/exprs/aggregate-functions-ir.cc@1736 PS4, Line 1736: DS_SKETCH_CONFIG, DS_HLL_TYPE Do these configs matter, or they are overwritten during deserialization? My understanding is that we should be able to union sketches with different configs.
