@jmaldon1 My impression is that `clear` is called on a task's xcoms before it runs. This is to prevent data from a prior rerun from influencing the current task execution. This way a task's author can assume that that task's XComs are always in a blank slate, whether it's a run or a rerun. I'll have an opportunity to verify this impression soon and I'll be sure to report back and correct it if I'm wrong. I'll also let you know if I stumble across an understanding of `delete`. (A guess it's that it's called when the dagrun is deleted). -- This is an automated message from the Apache Git Service.
