Tim Armstrong resolved IMPALA-1798. ----------------------------------- Resolution: Duplicate Sounds like IMPALA-4242 > Very slow performance of Views on top of another Views > ------------------------------------------------------ > > Key: IMPALA-1798 > URL: https://issues.apache.org/jira/browse/IMPALA-1798 > Project: IMPALA > Issue Type: Bug > Components: Perf Investigation > Affects Versions: Impala 2.1, Impala 2.1.1, Impala 2.3.0 > Environment: Cluster 3 nodes Impala 2.1 > Reporter: Alex Finch > Priority: Minor > Labels: performance, planner > > Query from a view has about the same performance as a query from the source > table. If we have a VIEW on top of another VIEW (even CREATE view_2 AS SELECT > * FROM view_1) the performance is much slower, for more complex queries on > top of view_2, the compilation of the query actually never finishes. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
