Rui Wang commented on CALCITE-3612: ----------------------------------- I see. So the title is not meaning add those types to optimizer but just add to Calcite (Calcite is not only an optimizer). An suggestion: could you assign Jira to yourself to claim that there is ongoing work. It will potentially avoid duplicate work. > Add TIME/TIMESTAMP WITH TIME ZONE in optimizer > ---------------------------------------------- > > Key: CALCITE-3612 > URL: https://issues.apache.org/jira/browse/CALCITE-3612 > Project: Calcite > Issue Type: Sub-task > Components: core > Reporter: Zhenghua Gao > Priority: Major > Labels: pull-request-available > Time Spent: 1h 10m > Remaining Estimate: 0h > -- This message was sent by Atlassian Jira (v8.3.4#803005)
