AquaQ Analytics posted a video "AquaQuarantine: Vaex, Arrow, Parquet" on VIMEO

Vaex is an open source python library for analysing large on-disk datasets which are usually stored in Parquet or Arrow formats. It uses a number of techniques similar to kdb+. Matt Doherty of AquaQ Analytics has been executing some exploratory data analytics using Vaex and will give an overview of the technology and show some comparisons with kdb+ in relation to both querying and data storage formats.
