Workarounds

  1. 95% success Move large attributes (e.g., binary data, large strings) to the message body instead. The body has a 256 KB limit. Example: sqs_client.send_message(QueueUrl=queue_url, MessageBody=json.dumps({'data': large_data}), MessageAttributes={'attr1': {'DataType': 'String', 'StringValue': 'small_value'}}) 
    Move large attributes (e.g., binary data, large strings) to the message body instead. The body has a 256 KB limit. Example: sqs_client.send_message(QueueUrl=queue_url, MessageBody=json.dumps({'data': large_data}), MessageAttributes={'attr1': {'DataType': 'String', 'StringValue': 'small_value'}})
  2. 90% success If attributes are necessary, store large attribute values in S3 or DynamoDB and pass only a reference (e.g., S3 key) as the attribute value.

Dead Ends

Common approaches that don't work:

  1. 90% fail

    SQS检查的是未压缩的属性大小，压缩不会改变原始大小。

  2. 100% fail

    FIFO队列与标准队列具有相同的属性大小限制。
