Summary: Set PubsubIO batch size using builder
Key: BEAM-2660
URL: https://issues.apache.org/jira/browse/BEAM-2660
Project: Beam
Issue Type: Improvement
Components: sdk-java-gcp
Reporter: Carl McGraw
Assignee: Stephen Sisk
PubsubIO doesn't allow users to set the publish batch size. Instead the value
is hard coded in both the BoundedPubsubWriter and the UnboundedPubsubSink.
google's pub/sub is bound to a maximum of 10mb per request size. My company has
run into problems with events that are individually smaller than 1mb, but when
batched in the 100 or 2000 default batch sizes causes pubsub to fail to send
the event.
