Amazon SNS Bumps Message Size to 1 MiB – Finally!

Amazon SNS just quadrupled its message payload limit from 256 KiB to 1 MiB, so you can now push bigger data chunks through your topics without splitting payloads. This lands on both SNS Standard and FIFO, works with SQS, Firehose, and Lambda subscriptions, and is available across all AWS regions today.
