Large datasets tend to be distributed, non-uniform, and prone to change. Dask simplifies the process of ingesting, filtering, and transforming data, reducing or eliminating the need for a heavyweight framework like Spark.



Data Science at Scale with Python and Dask teaches readers how to build distributed data projects that can handle huge amounts of data. The book introduces Dask Data Frames and teaches helpful code patterns to streamline the reader's analysis.



Key Features



Working with large structured datasets
Writing DataFrames
Cleaningand visualizing DataFrames
Machine learning with Dask-ML
Working with Bags and Arrays



Written for data engineers and scientists with experience using Python. Knowledge of the PyData stack (Pandas, NumPy, and Scikit-learn) will be helpful. No experience with low-level parallelism is required.



About the technology

Dask is a self-contained, easily extendible library designed to query, stream, filter, and consolidate huge datasets.
