Handling large SQS message payloads

Webflow's engineering team faced challenges with Amazon SQS's 256 KB payload limitation while handling large webhook data events, crucial for maintaining real-time data synchronization across platforms. To address this, they extended their SQS client interface to store oversized messages in Amazon S3, leveraging its large storage capacity, scalability, and cost-effectiveness. This approach involved updating message headers with pointers to S3 locations, allowing seamless retrieval without altering the SQS message producers or consumers across their products. By implementing S3 lifecycle policies for automatic deletion, they improved performance and reduced network calls, achieving a 100% success delivery rate for over 13,500 large payload webhooks. Future optimizations include exploring data compression to enhance network performance and storage efficiency, reflecting Webflow's commitment to offering robust infrastructure and inviting interested individuals to join their team.
