Thanks for the write up and your interest. I have a few questions: - What about schema column names that cannot be struct fields in Rust? - How do you...
I would like to see the code, because you are using existing record assembly machinery and seeing these improvements. I am curious to what changes you have made to improve...
Allocation of what? How do you avoid allocation - you need to return rows? Are you using a mutable row reference instead?
What do you mean by upcast? Those are completely different structs. Could you elaborate on this comment? ```rust typed_writer.close().unwrap(); // doesn't stop row_group_writer from complaining a column is still open...
If your code needs to have that method, we can keep it public and fix the code around it. The easiest would be making it private with it's counterpart in...
Thanks for writing the comment. I have been snowed under with the current project, so apologies for that. I quite like your idea, it is a bit different from mine....
We have similar thing in record reader.
How will you add it to the encoder or decoder? They don’t have information about null values - they encode or decode non null values. If I am not mistaken...
I suggest adding an item to update the existing doc to reflect the addition of arrow reader/writer.
Have you read the documentation? Was it clear how to use column writers and row group writers? From definition: `Because of this recursive dropping, you do not need to implement...
