Then users, including ecosystem developers, have to dig into the implementation details. I don't like saying that these developers use Pulsar in a wrong way. I'd like to say they are limited by the poor interface that Pulsar provided. Keeping the limitation is harmful to the Pulsar community and could make ecosystem applications flaky and easy to break. -- This is an automated message from the Apache Git Service.
