    o

    Object that contains message JoinWithTimeInfo JoinWithTimeInfo contains attributes as follows:

    • timeColName: Column name containing time information (required)
    • keyColName: A list of column names to be used as group by keys (required)
    • timeInterval: size of time slot in seconds or minutes. (required)
    • joinType: Type of join (optional)

    JoinWithTimeInfo

    message JoinWithTimeInfo {
     optional string timeColName = 3;
     repeated string keyColName = 4;
    required string timeInterval = 3 [default = "1 minutes"];
    optional JoinType joinType = 4 [default = INNER];
    }

    JoinType

    enum JoinType {
    INNER = 0;
    LEFT_OUTER = 1;
    RIGHT_OUTER = 2;
    }
