What are the key differences between Dask and Spark?

Dask and Spark are both powerful tools for big data processing, but they have different strengths. Dask is more Pythonic and integrates well with NumPy and Pandas, while Spark is optimized for distributed computing and can handle larger datasets across clusters.

Which one is better for machine learning tasks?

It depends on your specific needs. Dask is great for smaller datasets and integrates seamlessly with scikit-learn, while Spark's MLlib is designed for large-scale machine learning tasks.

Can you give examples of use cases for each?

Sure! Dask is often used for data analysis and manipulation in Python, while Spark is commonly used for large-scale data processing tasks like ETL and real-time analytics.

What about performance? Which one is faster?

Performance can vary based on the task and dataset size. Generally, Spark is faster for large-scale data processing due to its optimized execution engine, but Dask can be more efficient for smaller, in-memory computations.
