In the early 2000s, Java became the language of choice for Big Data applications. However, a new era has arrived with technological developments and breakthroughs in CPU architecture and network capabilities, bringing a fresh perspective to programming languages. Known for its emphasis on performance, safety, and concurrency, Rust has made a name for itself. This blog delves deep into Rust’s transformative potential for Big Data applications and parallel processing scenarios.

As industries grapple with increasingly large data sets and the need for efficient parallel processing, Rust emerges as a compelling candidate to deliver powerful and modern solutions to the challenges of Big Data. Join us as we explore how Rust is shaping the future of data-intensive computing.

Why Choose Rust for Big Data Applications?

Rust stands out as a strong choice in Big Data and parallel processing for several compelling reasons:

Performance Prowess:

Rust emphasizes zero-cost abstraction and efficient memory management to ensure high-performance execution, which is critical for processing large data sets and parallel workloads.

Concurrency without Compromise:

Rust’s ownership system facilitates concurrent programming without sacrificing safety, enabling developers to write efficient and reliable concurrent code.

Memory Safety:

The ownership model, borrow checker, and strict compiler checks make Rust inherently memory-safe, mitigating the risk of memory-related bugs often encountered in complex data processing applications.

Ecosystem and Tools:

Rust’s growing ecosystem and strong tooling support make it ideal for developing and maintaining large-scale data applications, providing developers with the resources they need for effective Big Data processing.

Predictable and Reliable:

Rust’s focus on deterministic performance and error prevention enhances application predictability and reliability, key attributes for parallel processing tasks requiring consistent and reliable execution.

Ongoing Projects in Big Data and Parallel Processing that Use Rust

Apache Spark

Apache Spark stands out as one of the most widely adopted tools in Big Data, leveraging a JVM-based architecture. In his blog post “Rust is for Big Data,” Andy Grove, Apache Arrow PMC Chair, shares insights from his extensive field experience. As well as, having routinely worked on constructing distributed data processing jobs using Apache Spark, he identified areas for potential efficiency improvements.

Grove highlights the remarkable engineering efforts invested in Spark to address efficiency issues and minimize its reliance on the JVM. He contends that adopting a language like Rust could enhance Apache Spark’s efficiency. Inspired by this vision, Grove initiated the open-source project named ‘Data Fusion,’ which was eventually embraced by the Apache community.

Data Fusion

Data Fusion has evolved into an in-memory query engine utilizing Apache Arrow as its memory model. Facilitating the execution of SQL queries on CSV and Parquet files and direct queries on in-memory data, Data Fusion is a collaborative effort involving both the Apache and Rust communities.


Weld is a Rust-based project that makes code for data analysis processes. It works well when run in parallel with the LLVM compiler framework. Also, MIT CSAIL experts say that in many data analysis workflows, moving data between parts takes a lot of time that could be used for processing. Weld solves this problem by making a runtime that tools can easily connect to. This provides a standard way to optimize and parallelize important data across the pipeline. Weld also improves the performance of the different parts of a current data processing stack. It is known as a common runtime for data analytics.

Rust Libraries for Data Processing

Rust emphasizes performance, memory safety, and concurrency and has entered the field of Big Data applications. Also, several frameworks have emerged to leverage the power of Rust for efficient and scalable data processing. Notable among them are:

Noria: Designed specifically for real-time analytics, Noria focuses on maintaining materialized views for high-throughput data processing.

Polars: Polars is a DataFrame library that facilitates fast and expressive data manipulation, making it ideal for complex analytical tasks.

Tangram: Focused on machine learning, Tangram enables the creation of predictive models, providing a seamless experience for developers in the field of data-driven insights.

Timely Dataflow: Leveraging Rust’s ownership system, Timely Dataflow provides a data-parallel computing engine that enhances the scalability and efficiency of large-scale data processing.

RustyHermit: RustyHermit provides isolation for concurrent applications, enhances the security and reliability of Big Data systems, and ensures a robust and stable environment for data-intensive tasks. 

These Rust libraries exemplify the language’s versatility and effectiveness in the Big Data world.

Big Data Tools Built Using Rust

Many cutting-edge data tools have been made in Rust, demonstrating the language’s versatility and efficiency. Here are some prominent examples:

Arrow: Apache Arrow, a development platform for in-memory analytics, stands out for its power in handling data-intensive tasks.

Polars: It is an exceptionally fast DataFrames library, implemented in Rust using the Apache Arrow format as the in-memory model, enabling developers to perform fast and expressive data manipulation.

Meilisearch: Known for its speed and hyper-relevance, Meilisearch is an advanced search engine that provides a RESTful search API for seamless integration.

DataFusion: DataFusion is a scalable query execution framework written in Rust and using Apache Arrow as its in-memory format. It excels at creating modern, high-speed data pipelines, ETL processes, and robust database systems. These Rust-built tools exemplify the language’s strength in developing complex and efficient solutions for a variety of data-centric applications.
