We can directly convert to Delta right? Why using CSV->parquet->Delta format? Why not Dataframe->DeltaFormat?

This is really great content
Why we are converting the csv to parquet in the beginning, can't we direct change the csv to delta?
As u know, there are still some project which uses target as parquet and wanting to convert to delta.. this is one of usecase that deal with conversion.. so to create a parquet, we use CSV in first.. hope u got it
