Design a large scale NoSQL/DataGrid application similar to Twitter with Nati Shalom (Founder and Chief Technology Officer at GigaSpaces). Nice session taking you through some of the challenges that you'll be facing when designing a twitter like application. I.e. What is needed when one wants to build a high performance, highly scalable system on which extensive data analysis can be performed as well. It answers on the type of components that will be needed.
The use case is solved with Gigaspaces and Cassandra but other NoSQL and DataGrids solutions could be used.
