Kenneth Knowles reassigned BEAM-3616:
-------------------------------------
Assignee: (was: Kenneth Knowles)
> Ensure coders are updatable partially in a cluster (aka add versions to
> coders)
> -------------------------------------------------------------------------------
>
> Key: BEAM-3616
> URL: https://issues.apache.org/jira/browse/BEAM-3616
> Project: Beam
> Issue Type: Improvement
> Components: sdk-go, sdk-java-core, sdk-py-core
> Reporter: Romain Manni-Bucau
> Priority: Major
> Fix For: 3.0.0
>
>
> Follow up ticket for the following discussion:
> https://lists.apache.org/thread.html/f3b2daa740075cc39dc04f08d1eaacfcc2d550cecc04e27be024cf52@%3Cdev.beam.apache.org%3E
> Long story short: seems being able to update a live stream is a constraint
> beam must address. This implies no change in coder serialization. To do it
> the only way is to put a marker (like a version) otherwise the live update
> will be broken if part of a cluster is updated only.
> This task is about ensuring we support it.
