Apache Arrow Explained by Voltron Data's Matt Topol - Subsurface 

You are a genius! Fantastic explanations! Thanks!

Good explanation of what arrow is and what it is used for

Apache Arrow is an in-memory representation of data to avoid copying for repeated serialization and deserialization.

Great!!!

How filters on data will work in arrow as it is columnar db?

It's a shame, really: the explanation is good and the topic is interesting, but the sound quality is absolutely atrocious. Sometimes it's difficult to even distinguish which tech is he referencing...
