Comment on Delta Lake vs. Parquet: A Comparisonparent

Comments

Looking at this now.

* Delta Lake supports merge-on-read via deletion vectors: https://delta.io/blog/2023-07-05-deletion-vectors/

* Why doesn't Delta Lake have efficient bulk load? Lots of the biggest datasets in the world are in Delta tables.

* Delta Lake definitely supports compaction: https://delta.io/blog/2023-01-25-delta-lake-small-file-compa...

* What does CLI support mean in the context of a Lakehouse storage system? You can open up a Spark shell or Python shell to interface with your Delta table. That's like saying "CSV doesn't have a CLI". I don't get it.

I didn't do a detailed review of the post.
