Did you set up Kafka Outbox yourself?

Yes, I configured Kafka Outbox myself.

Kafka Outbox is a pattern that helps ensure the atomicity of writing to the database and publishing events to Kafka. It is usually implemented through a separate outbox table in the database, where events are recorded along with the main transaction. Then, a separate process reads these events and publishes them to Kafka.

An approximate setup algorithm:

1. Create an outbox table with fields for storing the event (payload, type, status).
2. During the transaction, along with the main business operation, record an event in the outbox.
3. A separate worker periodically reads new entries from the outbox and publishes them to Kafka.
4. After successful publication, it updates the record's status in the outbox.

This helps prevent desynchronization between the database and the message broker.

In Go, you can use libraries for working with Kafka (e.g., segmentio/kafka-go) and standard database drivers.
