Subject Re: Direct control over where data is stored?

Please give more detailed info about what exactly you are worried about or
trying to solve.

Please take a step back and look at cassandra's architecture again and what
it's trying to solve. It's a distributed database so if you do what you are
describing there is a potential of getting hotspots. Which will probably
lead in other problems. You might solve one problem but then intriduce
another like slow reads or one node getting overloaded.

IF you really want to do what you described you can solve it simply by
designing your data model in that way. For eg: For User A you can store
information for all it's friends. This will lead to duplicate data but will
solve your problem.

I also suggest run some stress test and worry about the load, performance
only if it is a real problem for your kind of data.
