    Microservice provides an outbox table within its database.

    Outbox table will include all the events.

    ▪ There will be a CDC (change data capture) plugin that reads the commit log of the outbox table and publish the events to the relevant queue.

    ▪ It provides that messages are reliably delivered from a microservice to another microservice even if the transaction that triggered the message fails.

    ▪ It involves storing the message in a local "Outbox" table within the microservice, that message sent to the consumer after the transaction is committed.

    ▪ Outbox pattern can be used to ensure that messages are delivered consistently, even if the microservice that sent the message is unavailable or experiencing errors.

    ▪ Useful for communicating important information or updates between services
