It mirrors the behavior of the Java library amazon-sns-java-extended-client-lib, allowing you to set a bucket name and optional size threshold on SNS client, Topic, or PlatformEndpoint objects, then publish normally\u2014the library intercepts and routes large payloads to S3 transparently.\n\nThe package supports configurable thresholds (default 262144 bytes, minimum 0, maximum 262144), legacy message attributes for backward compatibility with older Java client versions, custom S3 clients with specialized configurations, and custom S3 keys via message attributes. It works with boto3's low-level SNS client, Topic resources, and PlatformEndpoint resources, and requires only that the target S3 bucket already exists and is accessible.","worth_installing":"Yes, if you need to publish messages larger than SNS's direct limit and have S3 available. The library is stable (production classifier, latest release 2025-02-18), has low install friction (one dependency), and carries no known vulnerabilities. Maintenance is dormant but the codebase is small and the underlying AWS APIs are stable. Verify that your subscriber infrastructure can handle S3 reference resolution before deploying."},"id":"amazon-sns-extended-client","links":{"html":"https://skillfed.io/packages/amazon-sns-extended-client","md":"https://skillfed.io/packages/amazon-sns-extended-client.md","pypi":"https://pypi.org/project/amazon-sns-extended-client/"},"maintenance":{"status":"dormant"},"meta":{"latest_release":"2025-02-18","license_spdx":null,"license_treatment":"permissive","name":"amazon-sns-extended-client","python_support":"supports_current","summary":"Python version of AWS SNS extended client to publish large payload message"},"popularity":{"monthly_downloads":158539,"position":10718,"tier":"top_15000"},"security":{"n_vulnerabilities":0},"version":"1.0.1"}
