Giraph – What is it ? • Graph processing for Hadoop V2 • For tasks that dont fit Map Reduce • Better performance for those tasks • Processing by interations called super steps • Uses Bulk Synchronous Parallel computing ( BSP ) • See Apache Hama presentation • Licensed via Apache • For distributed computing • For massive calculations www.semtech-solutions.co.nz info@semtech-solutions.co.nz
Giraph – How does it work ? • Consider example • Input is chain graph • Find shortest path • Three super steps • Vertices have values • As do edges • Messages between steps www.semtech-solutions.co.nz info@semtech-solutions.co.nz
