Paul Rogers created IMPALA-8258: ----------------------------------- Summary: Enhance functional tables with realistic star-schema simulation Key: IMPALA-8258 URL: https://issues.apache.org/jira/browse/IMPALA-8258 Project: IMPALA Issue Type: Improvement Components: Frontend Affects Versions: Impala 3.1.0 Reporter: Paul Rogers Assignee: Paul Rogers
The tables in the `functional` db provide many interesting cases. The tables in TPC-H and TPC-DS simulate a well-behaved application. We also need some tables that show messy, real-world cases: * Correlated filters (same filter on multiple tables) * Correlated keys (same join key across multiple tables) * Extreme data skew A simple four-table start-schema structure can give us what we want. -- This message was sent by Atlassian JIRA (v7.6.3#76005) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-all-unsubscr...@impala.apache.org For additional commands, e-mail: issues-all-h...@impala.apache.org
