Apache Spark in some cases, which means that more processing can fit on a single node, reducing the overhead of
distributed compute.
- The use of Apache Arrow as the memory model and network protocol means that data can be exchanged efficiently between
executors using the [Flight Protocol](flight), and between clients and schedulers/executors using the

## Features

- Supports HDFS as well as cloud object stores. S3 is supported today and GCS and Azure support is planned.
- DataFrame and SQL APIs available from Python and Rust.
- Clients can connect to a Ballista cluster using [Flight SQL](flight-sql).
