Hi,
I know about MapReduce/Hadoop and trying to get myself around
BSP/Hama-Giraph by comparing MR and BSP.
- Map Phase in MR is similar to Computation Phase in BSP. BSP allows for
process to exchange data in the communication phase, but there is no
communication between the mappers in the Map

Thanks to Thomas and Avery for the response.
For Giraph you are quite correct, all the stuff is submitted as a MR
job. But a full map stage is not a superstep, the whole computation is a
done in one mapping phase.
So a map task in MR
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
