# Apache Giraph

**Canonical:** https://apis.io/providers/apache-giraph/  
**APIs profiled:** 3

Apache Giraph is an iterative graph processing system built for high scalability on Apache Hadoop. It is modeled after Google's Pregel and provides a simple yet flexible Java API for graph algorithms at massive scale using the Bulk Synchronous Parallel (BSP) model. Note - Apache Giraph has been retired as of 2024.
