Yes I think it is beneficial to avoid dropping buffers with `seek`, although it will be nice if the `seek_relative` will be stabilized soon so we can just use that. > Also, I'm not sure why a Mutex was used here. Do we agree that Refcell is better as the whole reader is not thread safe, right ? [Originally](https://github.com/sunchao/parquet-rs/pull/49) we designed it this way so that we can concurrently read multiple column chunks after obtaining file handle from a single row group. Since the file handle is shared between these we wanted to provide thread safety on top of it. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
