Summary: Fix mapjoin size estimations for Fast implementation Key: HIVE-20491 URL: https://issues.apache.org/jira/browse/HIVE-20491 Project: Hive Issue Type: Improvement Components: Statistics Reporter: Zoltan Haindrich Assignee: Zoltan Haindrich HIVE-19824 have fixed the estimations; but it calculated for the "optimized" impl; the "fast" one has a little bit bigger footprint. It also seems like fast is a bit overestimated at runtime...that should be also taken care of. | numkeys | implementation | compiler estimation | runtime estimation | runtime measurement | ce / rm | re / rm | | 25M | FAST | 1168435456 | 2189433712 | 1513584984 | .77 | 1.44 | | 25M | OPTIMIZED | 1168435456 | 1191203764 | 1168439664 | 100% | 1.01 | -- This message was sent by Atlassian JIRA (v7.6.3#76005)
