In Memory Message Store is the default Message Store that will be created if user does not specify any implementation from the configuration. Messages will be stored in an in-memory queue. So in case of a ESB restart, all the messages stored will be lost.

In Memory Message Store is lot faster than a persistent message store implementation, so it can be used as a temporary storage of messages for use cases such as the implementation of a high-speed store and forwarded patterns where message persistence is not a requirement.

Note

In memory message stores are not recommended for use in production as well as in scenarios where large scale message storing is required. You can use an external message store (e.g., JMS message store) for such scenarios.
