Efficient Data Handling in Python with Arrow | Towards Data Science

1. Introduction We’re all used to work with CSVs, JSON files… With the traditional libraries and for large datasets, these can be extremely slow to read, write and operate on, leading to performance bottlenecks (been there). It’s precisely with big amounts of data that being efficient handling the data is crucial for our data science/analytics workflow, and this is exactly where Apache Arrow comes into play.  Why? The main reason resides in how the data
