Kafka Connect is a powerful framework for building streaming pipelines between Kafka and other technologies, including databases, message queues, and flat files. It can be used for both reading data from Kafka into other systems and writing data to Kafka from other systems. The key feature of Kafka Connect is its ability to handle errors in a configurable way, allowing developers to choose how their pipeline handles errors. This includes the option to route failed messages to a "dead letter queue" where they can be inspected and potentially fixed before being reprocessed. The dead letter queue allows for more control over error handling and provides valuable insights into what's causing errors in the pipeline.
