Abstract: A distributed database system maintains data for a database client by storing data on a plurality of storage nodes. Upon receiving a request from the database client in a first format, the database system translates the request to a second format and sends the translated request to a storage subsystem. The storage subsystem generates an exception if the translated request cannot be successfully completed. The distributed database system resends the translated request on behalf of the database client if the exception corresponds to a request that can be retried, and continues to resend the translated request until a first of an expiration of a predetermined time period or until the request completes successfully. The distributed database system sends a response to the database client based on the resent database request.
