API Error Codes
There are two types of error codes, client and server.
Client error codes are generally caused by the client and might be an authentication failure or an invalid domain; these errors are accompanied by a 4xx HTTP response code.
Server error codes are generally caused by a server-side issue and a large volume of server error codes should be reported to Amazon Web Services (including the request ID and the time when the request was issued); these errors are accompanied by a 5xx HTTP response code.
About Response Code 503
Typically, a large volume of server error codes (5xx) should be reported to Amazon Web Services with one exception: response code 503. A response code 503 indicates that applications are submitting too many requests to Amazon SimpleDB in a very brief span of time. So, while other server error codes (5xx) indicate a distinct server problem, a 503 response code does not indicate a problem with Amazon SimpleDB, specifically, and should be resolved on the client side.
To resolve response code 503, implement request retries in the client application with exponential backoff. For details, see API Error Retries. Or, split your domain into multiple shards to achieve better parallelism and higher throughput.
