Summary: Adding endpoint support in Pubsub Source / Sink
Key: FLINK-25787
URL: https://issues.apache.org/jira/browse/FLINK-25787

Multi-regional or “global” outages affect only the regions where you have
running publishers. If you have an application publishing from regions A, B and
C and regions A and B go down, the application in region C is unaffected. At
the same time, traffic from applications in A and B is not load-balanced out to
C or another region. This is because Pub/Sub deliberately keeps traffic within
the region to prevent cascading failures. An exception to this is traffic from
outside of the GCP network connecting to Pub/Sub’s global service
endpoint{noformat}
Example:
If Google Pubsub in region "us-central1" down then the application running in
same region with global endpoint ({{{}pubsub.googleapis.com{}}}.) will not be
able to connect to Google pubsub. But if we use regional endpoint to connect to
Google pubsub in another region (say: us-east1) will work.
So we should expose option to set regional endpoint in Source/Sink.
