Amazon SNS introduces an open-source extended client library in Python. It allows you to publish and deliver large message payloads automatically by saving the actual payload in an Amazon bucket. It provides high-throughput push-based communication functionality for many-to-many message distribution.
The library is useful for application-to-application and application-to-person communication. Larger payload transmission will only incur one billing payload-based amount per Amazon SNS request, and the payload data is stored in Amazon bucket.
