Reference documentation and code samples for the Cloud PubSub V1 Client class ApiViolationReason.
Specifies the reason why some data may have been left out of
the desired Pub/Sub message due to the API message limits
(https://cloud.google.com/pubsub/quotas#resource_limits). For example,
when the number of attributes is larger than 100, the number of
attributes is truncated to 100 to respect the limit on the attribute count.
Other attribute limits are treated similarly. When the size of the desired
message would've been larger than 10MB, the message won't be published at
all, and ingestion of the subsequent messages will proceed as normal.
