Apache Arrow is 10 years old

The data standard powering AI/ML just proved its decade-long durability...

Deep Dive

Apache Arrow celebrates its 10th anniversary, having maintained remarkable backward compatibility since its first release in 2016. The columnar data format, crucial for AI/ML and analytics, has seen only one minor breaking change in a decade—removing top-level validity bitmaps for Union types in 2020. Originally created as an in-memory complement to Parquet, Arrow now enables efficient data exchange across Python, Java, C++, and other languages, with integration tests ensuring cross-language consistency since late 2016.

Why It Matters

This stability means the foundational data layer for modern AI tooling won't break your pipelines as new models emerge.
