Aligning Velox and Apache Arrow: Towards composable data management

What this post added

This post details the convergence of Meta's open-source execution engine, Velox, with Apache Arrow. It introduces three new Arrow format layouts (StringView, ListView, and Run-End-Encoding) inspired by Velox's internal representations. These additions aim to improve interoperability and efficiency in data management systems by enabling zero-copy in-memory data transfer and supporting out-of-order writes for variable-sized data types, contributing to a more composable data management architecture.
