Summary: Implement support for size-estimation aggregators
Key: BEAM-460
URL: https://issues.apache.org/jira/browse/BEAM-460
Project: Beam
Issue Type: Bug
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.
