To scale pandas DataFrames and NumPy arrays beyond memory limits, use distributed computing to partition data into chunks and process tasks in parallel across available cores or a cluster.

Lazy evaluation in parallel data processing builds task graphs to defer computation until explicitly requested, enabling scalable workflows by optimizing complex data movement and memory usage for large datasets.

Yes, you can process unstructured data using Bags and manage dynamic task scheduling with Futures, enabling flexible distributed computing workflows across cores or a configured cluster environment.

Yes, a configured Dask environment, either local or distributed, is required to run parallel computations, along with guidance on chunking, scheduling, and integrating ecosystem tools like XArray and Dask-ML.

Limitations of distributed computing include the need for careful chunking, complex data movement management, and scheduler configuration overhead, which can introduce latency and require cluster environment tuning.

To read multiple CSV files and compute aggregations in a distributed environment, use parallel DataFrame readers like dd.read_csv to load data lazily and apply aggregation functions across partitions.
