Hi @Patrick539, I've opened #76220 for this, using the shared parser approach from my last comment. Your chain should now work with the default settings: a key can go through `StartOfHourMapper`, then `StartOfDayMapper`, then `StartOfYearMapper` in separate Dags. `StartOfYearMapper` also accepts the default output of the week, month and quarter mappers, as you described. There are two limits to be aware of: * If a mapper uses a custom `output_format`, the next mapper still needs a matching `input_format`. * Mappers used inside a `RollupMapper` still accept only their `input_format`, because those are the exact keys the rollup waits for. Accepting other formats could hold the Dag run forever. If you have time, it would be great to know whether this covers your use case. The open questions are listed in the PR, and any feedback on them is welcome. -- This is an automated message from the Apache Git Service.
