public @interface Idempotent

IdempotentReceiver ensures that only unique messages are received by a component. There are different types of idempotency handlers:

• ID - Checks the unique ID of the incoming message. Note that the underlying endpoint must support unique message Ids for this to work, otherwise a UniqueIdNotSupportedException is thrown.
• HASH - Calculates the SHA-256 hash of the message itself. This provides a value with an infinitesimally small chance of a collision.
