Amazon Simple Notification Service (Amazon SNS) now supports additional message filtering capabilities, including the ability to match against characters at the end of a value (suffix matching), to ignore case sensitivity (equals-ignore-case matching), and to have a single filter match if any conditions across multiple separate message properties are true (OR matching). You can leverage these new filtering operators to further simplify your messaging architecture by offloading additional message filtering logic from subscribers, as well as message routing logic from publishers.
