akimbo

For when your data won't fit in your dataframe

Akimbo provides fast, vectorized processing of nested, ragged data in dataframes, using the `.ak accessor.


Features
numpy-like API for slicing and accessing data deep in nested structures
apply any function, ufunc or aggregation at any level
use with different backends: pandas, polars (lazy and eager),
  dask-dataframe, pyspark, duckDB and cuDF
  exactly the same way (more backends may come in the future)

CPU and GPU processing and support for numba`-jit
attach object-like behaviours to your record (sub)structures

See the quick start in the documentation for an introduction to akimbo.
