Integrates with existing projects

-

Built with the broader community

-

Dask is open source and freely available. It is developed in coordination with other community projects like NumPy, pandas, and scikit-learn.

-
- -
-

NumPy

- -

Dask arrays scale NumPy workflows, enabling multi-dimensional data analysis in earth science, satellite imagery, genomics, biomedical applications, and machine learning algorithms.

Familiar for Python users

-

and easy to get started

-

Dask uses existing Python APIs and data structures to make it easy to switch between NumPy, pandas, scikit-learn to their Dask-powered equivalents. -

You don't have to completely rewrite your code or retrain to scale up.

- -
-
# Arrays implement the NumPy API
-import dask.array as da
-x = da.random.random(size=(10000, 10000),
-                     chunks=(1000, 1000))
-x + x.T - x.mean(axis=0)
- -
# Dataframes implement the pandas API
-import dask.dataframe as dd
-df = dd.read_csv('s3://.../2018-*-*.csv')
-df.groupby(df.account_id).balance.sum()
- -
# Dask-ML implements the scikit-learn API
-from dask_ml.linear_model \
-  import LogisticRegression
-lr = LogisticRegression()
-lr.fit(train, test)

Scale up to clusters

-

or just use it on your laptop

-

Dask's schedulers scale to thousand-node clusters and its algorithms have been tested on some of the largest supercomputers in the world.

- -

But you don't need a massive cluster to get started. Dask ships with schedulers designed for use on personal machines. Many people use Dask today to scale computations on their laptop, using multiple cores for computation and their disk for excess storage.

Customizable

-

Enabling you to parallelize internal systems

-

Not all computations fit into a big dataframe.

-

Dask exposes lower-level APIs letting you build custom systems for in-house applications. This helps open source leaders parallelize their own packages and helps business leaders scale custom business logic.
