------------------------------------

             Summary: Allow definition of quasi-monotonic columns
                 Key: CALCITE-1096
                 URL: https://issues.apache.org/jira/browse/CALCITE-1096
             Project: Calcite
          Issue Type: Bug
            Reporter: Julian Hyde
            Assignee: Julian Hyde


As discussed in CALCITE-1090, Calcite can make progress on streaming queries if 
columns are not monotonic but are slightly out of order and the stream has a 
mechanism (say watermarks or punctuation) to state that a particular value will 
never be seen again. We need to add support for this in the schema SPI.
