Dask vs Vaex – a qualitative comparison

“Vaex is flat out the fastest and most memory efficient Python DataFrame library out there…. There are still plenty of computational tasks in data science and even more in data engineering which can not be done in an out-of-core manner…. This is where Dask shines. Since it is a general framework for distributed computing, it can generalize well outside the domain of tabular datasets.”
