[erlang-questions] Large scale deployments testing

[Zhemzhitsky Sergey]

Hello gurus,

We’re developing a riak-core application, that does not include any persistence and works in-memory, and are wondering what are the best use cases to test riak-core and erlang itself in large-scale deployments (>100 physical nodes).

For example some of the map-reduce frameworks (like hadoop) have performance tests like terasort, etc., which can show to what extent the whole framework can be scaled.

So could you share some ideas what are the best practices to test large-scale deployments of riak-core and erlang applications? What synthetic tests and benchmarks can be executed to answer the following questions:


1.       Does the system scale well?

2.       Can the system be considered as linearly scalable?

3.       Is the system truly fault-tolerant?

Best Regards,
Sergey
