Amazon Relational Database Service (Amazon RDS) now supports the delivery of message attributes, which provide structured metadata about a message. Amazon RDS event attributes are separate from the message, but are sent with the message body. The message receiver can use this information to decide how to handle the message, enabling routing and filtering without having to process the message body first.
With Amazon Simple Notification Service (SNS) or Amazon Simple Queuing Service (SQS) you can now consolidate multiple filters for each condition into a single topic subscription. Amazon SNS and Amazon RDS events with attributes allow you to offload the message filtering logic from subscribers and the message routing logic from publishers. Each subscriber receives and processes only the messages accepted by its filter policy.
Amazon RDS event attributes are now available in Amazon Web Services China (Beijing) Region, operated by Sinnet, and Amazon Web Services China (Ningxia) Region, operated by NWCD. For more information about Amazon RDS events and attributes, see Working with Amazon RDS event notification. For more information on filtering, see Amazon SNS Message Filtering.
