What are some tips for optimizing performance in Vaex?

To optimize performance in Vaex, consider using lazy evaluation, filtering data early, and leveraging memory mapping.

Can you explain lazy evaluation and how it helps?

Lazy evaluation means computations are deferred until the result is needed, reducing memory usage and speeding up processing.

What about filtering data early? Why is that important?

Filtering data early minimizes the amount of data processed in subsequent operations, which can significantly enhance performance.

Are there any specific memory mapping techniques I should use?

Yes, using memory mapping allows Vaex to handle larger-than-memory datasets efficiently by loading only necessary parts into memory.
