MyCDC - MySQL change data capture

Application to run asynchronous operations based on DB changes. It is divided into three services:

  • RabbitMQ: Service that allows the exchange and queuing of messages between applications.
  • Producer: Reads and filters changes from the DB binary log and adds the relevant messages to each RabbitMQ queue.
  • Consumer: Obtains the elements from the queues and performs the necessary operations asynchronously.
