-------------------------------------

For the performance, there is an Eng Blog I found online written by Zoltán 
Borók-Nagy& Gábor Szádovszky. Here is the link

Once Spark is on Parquet 1.11.x, we can work on the Column Index for Spark 
Vectorized reader. Currently, I am working on integrating Column Index to 
Iceberg and Presto. The local testing on Iceberg also seems promising. 

> Parquet support Column indexes
