   > * Support for complex types. The parquet crate already supports reading 
maps and structs.
   
   @andygrove The doc here https://crates.io/crates/parquet says the reader 
supports ` Primitive column value readers`. Doesn't say whether complex types 
are supported.
   Also, something to keep in mind, Comet has Spark specific decoding (for 
instance Int96 timestamps 
https://github.com/apache/datafusion-comet/blob/00cf79b253d9fa31dcc0506facbaf7b2dac25cdd/native/core/src/parquet/read/values.rs#L841).
 Some post processing may need to be done unless we can hook in our own decoder 
for special cases like this.
