OK so, you are very much right. You should definitely benchmark it using a simulation of what your data might look like. It should not be that hard. Just make script, that creates bunch of files similar to your data. About the trailing white space, when I am in terminal I just use sed to remove the latest ‘\n’ and in rust I just use .trim(), in go I think there is strings.trim(). It is honestly not that hard. The data structure and parser is not formed the same way as the json, where you have to parse the whole thing. So you don’t have to. You just open the files you need read their content. It is a bit more difficult at first since you can’t just translate a whole struct directly, but it pays for itself when you want to migrate the data to a new format. So if your structure never changes, probably those formats are easier.
Sure thing! Awesome!
