Thanks for kicking this off, Leonard! As one of the contributors of the CDC project, I'm truly honored to be part of the community and so excited to hear the news. CDC project was born from and developed together with Apache Flink, and we are so proud to be accepted by more and more users around the world.
To put my Flink hat on, I believe having the CDC project as a part of Apache Flink will broadly expand our ecosystem and the usage scenarios. Both two projects will benefit from closer cooperation, so +1 from my side.
