| # Frequently Asked Questions |
| |
| ## What is the relationship between Apache Arrow, DataFusion, and Ballista? |
| |
| Apache Arrow is a library which provides a standardized memory representation for columnar data. It also provides |
| "kernels" for performing common operations on this data. |
| |
| DataFusion is a library for executing queries in-process using the Apache Arrow memory |
| model and computational kernels. It is designed to run within a single process, using threads |
| for parallel query execution. |
| |
| Ballista is a distributed compute platform built on DataFusion. |
