We start using Parquet file format in one of our projects for efficient storing 
of data to S3 and later querying of data in RedShift.
How do we make sure we use the latest version of Parquet and how to know what 
version is being supported by different query engines? (e.g. Presto, RedShift 

Is this a good place to track versions?

By looking at this video – it seems like version 2.x of Parquet format is in 
progress? https://www.youtube.com/watch?v=MZNjmfx4LMc

Also how can we know what version of Parquet is being supported by Spark 2.0 
and is it possible to change the parquet version (and how) in Spark?
And how would we know that different version of Parquet will work with 
different query engines..

Please refer me to some guide/blog if you have for some of the questions above.

Thank you,
Data Manager
