Avery,

Thanks for the response. Are there any open source frameworks for online querying of Graphs?

Hi Praveen,

You are right that Giraph is an offline graph computation infrastructure, not an online graph database. You could try using MySQL, HBase, Cassandra, etc for online querying.

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
