> Key: BEAM-460

> Project: Beam
> Issue Type: Bug
> Components: sdk-py
> Reporter: Charles Chen
> Assignee: Charles Chen
>
> Size-estimation aggregators are provided by the execution of each step in a
> Beam pipeline and help clarify the amount of data processed by each pipeline
> step. To ease implementation of this feature for runners, we should first
> expose size-estimation support for Coder objects. Runners can then use this
> functionality to implement full support for size-estimation aggregators.
