Arroyo is a distributed stream processing engine built in Rust, designed for real-time data analysis with stateful operations. It supports high-volume event processing, SQL-based pipelines, and can be run locally or in the cloud. Use cases include fraud detection and real-time analytics.

Grab has introduced a FlinkSQL interactive solution to enhance real-time stream processing for data analytics, addressing previous challenges with Zeppelin notebooks. The new architecture streamlines the user experience by integrating a shared FlinkSQL gateway, which reduces query lead times and simplifies the deployment of streaming pipelines, thereby democratizing data access and empowering teams to leverage real-time insights effectively.
