# Dask Best Practices

## Performance Optimization Principles

### Start with Simpler Solutions First

Before implementing parallel computing with Dask, explore these alternatives:
- Better algorithms for the specific problem
- Efficient file formats (Parquet, HDF5, Zarr instead of CSV)
- Compiled code via Numba or Cython
- Data sampling for development and testing

These alternatives often provide better returns than distributed systems and should be exhausted before scaling to parallel computing.

### Chunk Size Strategy

**Critical Rule**: Chunks should be small enough that many fit in a wo
