You didn't really explain it to a 5 year old. I am older than that, have experience with databases including low level storage, have a proven IQ level over the average but I am still at a lost after your video. So what does a parquet file look like physically? How do you create a parquet file? Answers to such questions are missing.
"it takes a long time to make a story short"
