[GitHub] [arrow-rs] tustvold commented on issue #3742: Support for Async JSON Writer

   Same as commented on the CSV writer ticket, https://github.com/apache/arrow-rs/issues/3740#issuecomment-1438682974, I would recommend implementing this by buffering an encoded batch in memory using the existing writer, prior to flushing it via async. This avoids code duplication, is more generic, and is likely significantly faster. It has been my experience that async does not optimise very well, especially in tight loops, and is best kept independent of the hot synchronous code.
