May 24, 2020 · The one pandas internal I teach all my new colleagues: the BlockManager. When new members join our team, they usually are already fluent in data analysis with pandas and know their way around the typical quirks. They know that they should use vectorised functions where possible and avoid using apply with a slow Python callable.
In the mailing list discussion on a simplified (non-consolidating) BlockManager, @jbrockmendel brought up the relevant question of how we could get there ...

Deep inside the belly pandas objects, there is a data structure called BlockManager which, at a high level, is responsible for managing the physical arrays ...
The primary benefit of the BlockManager is improved performance on certain operations (construction from a 2D array, binary operations, reductions across the columns), especially for wide DataFrames. However, the BlockManager substantially increases the complexity and maintenance burden of pandas. By replacing the BlockManager we hope to achieve
