Review comment:
Are we sure that 3600 sec will be enough for existing pipelines ? I would
not be surprised if some users have pipelines that will result in this being
exceeded. Can we keep the current default ?

> Add Cloud KMS support to GCS copies
> -----------------------------------
>
> Key: BEAM-5959
> URL: https://issues.apache.org/jira/browse/BEAM-5959
> Project: Beam
> Issue Type: Bug
> Components: io-java-gcp, sdk-py-core
> Reporter: Udi Meiri
> Assignee: Udi Meiri
> Priority: Major
> Time Spent: 3h 50m
> Remaining Estimate: 0h
>
> Beam SDK currently uses the CopyTo GCS API call, which doesn't support
> copying objects that Customer Managed Encryption Keys (CMEK).
> CMEKs are managed in Cloud KMS.
> Items (for Java and Python SDKs):
> - Update clients to versions that support KMS keys.
> - Change copyTo API calls to use rewriteTo (Python - directly, Java -
> possibly convert copyTo API call to use client library)
> - Add unit tests.
> - Add basic tests (DirectRunner and GCS buckets with CMEK).
