### Describe the usage question you have. Please include as many useful details as possible. The current recommendation is: "Now that Feather supports zero-copy reads into Arrow, the preferred approach would be to zero-copy read the file, add a column, then write a new Feather file" from https://issues.apache.org/jira/browse/ARROW-1518. This approach is quite costly. I'm very interested to know a more performant way. Thank you. P.S. I assume that I don't need to write usage details, as this problem is quite common if large data is stored in this format and needs to be updated. ### Component(s) Other -- This is an automated message from the Apache Git Service.
