   > One concern I have is that the current config also sets the number of maximum threads during reading parquet files.
   
   Is this still true though? I know we were creating threads at one point in time but we are using Tokio/async now, so we are not creating threads. Increasing partition count will increase the number of async tasks that we run in the thread pool but won't increase the number of threads.
