Gopal V created HIVE-9401: ----------------------------- Summary: Backport: Fastpath for limited fetches from unpartitioned tables Key: HIVE-9401 URL: https://issues.apache.org/jira/browse/HIVE-9401 Project: Hive Issue Type: Bug Components: Physical Optimizer Affects Versions: 0.14.0, 0.15.0 Reporter: Gopal V Assignee: Gopal V Priority: Minor Fix For: 0.15.0
Currently, for flat tables, the threshold check is applicable for a query like {{select * from lineitem limit 1;}}. This is not necessary as without a filter clause, this can be executed entirely via FetchTask. Running a cluster task is redundant for this case. This fastpath is applicable for partitioned tables already. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
