Best use case

dask is best used when you need a repeatable AI agent workflow instead of a one-off prompt.

Dask parallel computing library. Use for scaling pandas.

Teams using dask should expect a more consistent output, faster repeated execution, less prompt rewriting.

When to use this skill

You want a reusable workflow that can be run more than once with consistent structure.

When not to use this skill

You only need a quick one-off answer and do not need a reusable workflow.
You cannot install or maintain the underlying files, dependencies, or repository context.

# Dask

Dask scales Python. It looks like Pandas/NumPy but runs on clusters. 2025 updates focus on **High Performance Shuffle** and GPU integration.

## When to Use

- **Big Data**: When data > RAM but < BigQuery scale.
- **Cluster Computing**: Utilizing a Kubernetes cluster for Python functions.
- **Xarray**: Backend for geospatial data.

## Core Concepts

### Collections

`dask.dataframe`, `dask.array`, `dask.bag`.

### Scheduler

Decides where to run tasks (Local Threads, Processes, or Distributed Cluster).

### Dashboard

Real-time visualization of task progress (port 8787).

## Best Practices (2025)

**Do**:

- **Use `dask-expr`**: The new query optimization engine for Dask DataFrames.
- **Use Parquet**: CSVs are distinctively slow in distributed settings.

**Don't**:

- **Don't use for small data**: The overhead of the scheduler makes it slower than Pandas for <1GB.
