I think it would be better to use methods from the tempfile crate here, as is done elsewhere in this repo.

Specifically in arrow-avro/src/writer/mod.rs we should remove this code

And replace it with tempfile

For example:

https://github.com/apache/arrow-rs/blob/7f0aae9b9d20c49c86bfdaf53f689ae43d0237ac/arrow-ipc/src/reader.rs#L1847-L1846
