[GitHub] [arrow] mapleFU commented on issue #36005: [C++] [Parquet] StreamWriter should support writing nanosecond timestamps

   Emm I guess this should be easy but actually not so easy. Currently `StreamWriter` use `ConvertType` in parquet, and it was deprecated, and standard suggest using `LogicalType`. `ConvertType` doesn't support nano secs.
   
   Nano secs in supported when parquet 2.6 enabled, and only `LogicalType` supports nano secs.
   
   I'll take a look at how to add nano secs...
