The connector will store the history of the database schemas in Kafka using this broker (the same broker to which you are sending events) and topic name. Only changes in the inventory database will be detected. This name will be used as the prefix for all Kafka topics. ![]() If MySQL were running on a normal network, you would specify the IP address or resolvable host name for this value. Which is the name of the Docker container running the MySQL server ( mysql).ĭocker manipulates the network stack within the containers so that each linked container can be resolved with /etc/hosts using the container name for the host name. If any of the services stop or crash, those tasks will be redistributed to running services. The Kafka Connect service uses connectors to start one or more tasks that do the work,Īnd it automatically distributes the running tasks across the cluster of Kafka Connect services. Using a single connector task ensures proper order and event handling. Only one task should operate at any one time.īecause the MySQL connector reads the MySQL server’s binlog, ![]()
