             Summary: Add async write to AWS SNS IO & remove retry logic
                 Key: BEAM-8542
                 URL: https://issues.apache.org/jira/browse/BEAM-8542
             Project: Beam
          Issue Type: Improvement
          Components: io-java-aws
            Reporter: Ajo Thomas
            Assignee: Ajo Thomas


- While working with SNS IO for one of my work-related projects, I found that the IO uses synchronous publishes during writes. I had a simple mock pipeline where I was reading from a kinesis stream and publishing it to SNS using Beam's SNS IO. For comparison, I also had a lamdba which did the same using asynchronous publishes but was about 5x faster. Changing the SNS IO to use async publishes would improve publish latencies.
- SNS IO also has some retry logic which isn't required as SNS clients can handle retries. The retry logic in the SNS client is user-configurable and therefore, an explicit retry logic in SNS IO is not required
