Work on IMPALA-8258 started by Paul Rogers. ------------------------------------------- > 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 > Priority: Minor > > 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
