Package akka.javasdk.consumer

Interface Consumer.Effect

Enclosing class:

Consumer

public static interface Consumer.Effect

An Effect is a description of what the runtime needs to do after a message is handled. You can think of it as a set of instructions you are passing to the runtime, which will process the instructions on your behalf.

Each component defines its own effects, which are a set of predefined operations that match the capabilities of that component.

A Consumer Effect can either:

• return a message to be published to a Topic (when the Consumer is also a producer)
• return Done to indicate that the message was processed successfully
• ignore the message and continue processing the next message

For more details, refer to the Declarative Effects documentation.
