   For now, I'm thinking about adding a code to log the content of 
`parquet::ReaderProperties` and `parquet::ArrowReaderProperties`. 
   For example, the value of `pre_buffer` parameter has high impact with 
high-latency file systems. But sometimes that value is not explicitly set and 
user relies on the implicit default value for it. If a user then uses different 
API then it might end up using different value for the `pre_buffer` parameter 
and be unaware of it. With the logs I'm thinking about it would be much easier 
to track these situations down.
