ATTACHMENT ID: 12616842 > Better heuristics for worst case statistics estimates for join, limit and > filter operator > ----------------------------------------------------------------------------------------- > > Key: HIVE-5921 > URL: https://issues.apache.org/jira/browse/HIVE-5921 > Project: Hive > Issue Type: Sub-task > Components: Query Processor, Statistics > Affects Versions: 0.13.0 > Reporter: Prasanth J > Assignee: Prasanth J > Fix For: 0.13.0 > > Attachments: HIVE-5921.1.patch > > > This is a subtask of HIVE-5369. In worst case (i.e; absence of column > statistics) HIVE-5849 improved the basic statistics with heuristics. But the > heuristics failed to provide better estimates in few cases. For example: > FILTER operator heuristics did not take into account the number of predicates > and if the predicate contains partition column. Also, JOIN estimates were too > aggressive and was not user configurable. -- This message was sent by Atlassian JIRA (v6.1#6144)
