Flarion

Flarion is a data-processing acceleration company that speeds up distributed compute engines — Apache Spark, Hadoop, and Ray — without code or infrastructure changes. It ships an Arrow-native, DataFusion/Polars-based execution engine written in Rust that installs as a plugin in about six minutes, plus intelligent workload caching (query, data-block, and buffer caching) and a performance-monitoring platform for job metrics, resource tracking, anomaly detection, and failure prevention. Flarion runs on-premises or on Databricks, AWS EMR, GCP Dataproc, Azure HDInsight, and Anyscale, with an agentless architecture that requires no access to customer data, delivering roughly 3x performance and 60% cost savings. Flarion is a portfolio company of Sierra Ventures. The company exposes a product console and a legal/SLA surface but does not currently publish a public developer API, SDKs, or API documentation.

Flarion is profiled on the APIs.io network. Tagged areas include Company, Data, Data Processing, Apache Spark, and Big Data.

Flarion’s developer surface includes engineering blog, pricing, support, and 6 more developer resources.
