An example of this is getting data from Twitter to Elasticsearch by sending the data first from Twitter to Kafka and then from Kafka to Elasticsearch.
When we added Kafka Connect to Apache Kafka in version 0.9, it was after we saw Kafka used in both use cases at LinkedIn and other large organizations. We noticed that there were specific challenges in integrating Kafka into data pipelines that every organization had to solve, and decided to add APIs to Kafka that solve some of those challenges rather than force every organization to figure them out from scratch.
