I spent 6 hours learning Apache Arrow: Overview

Apache Arrow is a standard memory format designed for efficient data processing in analytics workloads. It focuses on performance and interoperability by leveraging a columnar in-memory format and aligned memory allocation. Arrow minimizes serialization and deserialization costs, enabling efficient data sharing between systems. Key elements include physical memory layouts for arrays, record batch serialization, and IPC formats enabling seamless inter-process and network data transfers. Arrow is widely adopted by various data projects, enhancing their performance and data handling capabilities.
