[GitHub] [arrow-rs] houqp commented on issue #455: Not able to read nano-second timestamp columns in 1.0 parquet files written by pyarrow

   pyarrow parquet writer has an option that one can set to write ns timestamp as `int96` for parquet 1.0, but is turned off by default. It is quite strange that decoded IPC schema comes back a `ns` type even though it's stored as `ms`.
