Jiang Xingbo created SPARK-22359: ------------------------------------ Summary: Improve the test coverage of window functions Key: SPARK-22359 URL: https://issues.apache.org/jira/browse/SPARK-22359 Project: Spark Issue Type: Test Components: SQL Affects Versions: 2.3.0 Reporter: Jiang Xingbo
There are already quite a few integration tests using window functions, but the unit tests coverage for window funtions is not ideal. We'd like to test the following aspects: * Specifications ** different partition clauses (none, one, multiple) ** different order clauses (none, one, multiple, asc/desc, nulls first/last) * Frames and their combinations ** OffsetWindowFunctionFrame ** UnboundedWindowFunctionFrame ** SlidingWindowFunctionFrame ** UnboundedPrecedingWindowFunctionFrame ** UnboundedFollowingWindowFunctionFrame * Aggregate function types ** Declarative ** Imperative ** UDAF * Spilling ** Cover the conditions that WindowExec should spill at least once -- This message was sent by Atlassian JIRA (v6.4.14#64029) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org
