Hi,

If I am not wrong Giraph is for batch processing similar to Hadoop. But, when I look for directions in Google Maps, the directions are returned within seconds. The 'shortest path algorithm' might be used. Are there any frameworks to get instantaneous results from graphs from distributed systems?

Praveen
