Hi, @ZENOTME Since we have finished the framework, I'm thinking about providing a high level api such as append in python first rather providing these low level apis, what do you think?

Sure. I can work on it later and add the e2e test for the writer. But can this work be done in parallel with low-level writers, seems there are someone interested in them.
