---------------------------------------
Summary: Throw unsupported error message for window functions
Key: DRILL-1912
URL: https://issues.apache.org/jira/browse/DRILL-1912
Project: Apache Drill
Issue Type: Bug
Components: SQL Parser
Affects Versions: 0.8.0
Reporter: Victoria Markman
Window functions below are currently:
* Supported in Calcite
* Not supported in DRILL
* Not documented in DRILL documentation
ROW_NUMBER()
FIRST_VALUE()
LAST_VALUE()
PERCENT_RANK()
DENSE_RANK()
Spoke to Jacques: Window function implementation is not targeted until after
1.0 release. Therefore, for 0.8.0 release we are going to throw "Unsupported"
error message for these functions as well as for every other function that
supports OVER clause due to two critical bugs below:
DRILL-1487 - window functions return wrong result
DRILL-1902 - new implementation of window functions
Assigning to Jacques on his request, targeting 0.8.0
