Hey guys, what I want to say is just an idea based on my experience.
Debezium is a great tool for CDC pipeline from databases to Kafka and it works awesome! based on my experiences companies need to store these data into fast analytical databases or time-series databases. the only available solution for that is using Confluent Kafka-Connect-JDBC connector that has lots of problems but important ones are:

1. not compatible with Debezium Types(it only support a few simple data types and in every company that I worked for that I had to adjust and maintain it)
2. not really user(customer?) friendly and there are lots of unanswered issues on their repository
3. not developer-friendly!(the developer needs to build confluent Kafka then confluent common to able to compile the connector)

I thought if the Debezium provides a way to capture data changes to Kafka it would be nice to also provide a way to consume this data to other databases as awesome as its source connectors.

The new sink connectors will make these advantages for us:

1. make customers/users happier!
2. better control on datatypes from source connectors.
