Hey Andy I want to discuss the areas of Ballista code that you proposed above to move to Arrow. The application could have used the DataFusion Table API to build the query as an alternative to using SQL: The application then runs a secondary query on the union of the results from the executors to arrive at the final aggregate result: Here is a video showing the current PoC in action. This Week in Ballista #11 18 Apr 2021. If you are interested in contributing to Ballista, we would love to have you! The cost of compute can be very high with Big Data platforms, so it makes sense to use a language that can make efficient use of the available memory and processing power on each node. 3 // distributed with this work for additional information. Many other bug fixes the project was donated to the Apache Arrow project DataFusion … There have been some discussions about supporting ML workloads but this is an area that I do not have experience with so I am hoping that once Ballista is a little more mature in terms of ETL processing then we can start to look at other areas like ML and listen to what the current pain points are.

JuliaSim is a cloud-based simulation platform built on top of the Julia open source stack, including SciML and ModelingToolkit. Arrow also provides a “Flight” protocol, designed to enable Arrow data to be streamed efficiently (without serde overhead) between processes, and Ballista’s executors implement this protocol. Priority: Major . Ballista is implemented in Rust and powered by Apache Arrow. Apache Spark is implemented in Scala and tends to have a Scala-first approach, with other languages paying a penalty to interact with Spark due to overheads of serde.
