Scalable ETS: Does Such a Thing Exist?

Erlang Term Storage (ETS) is Erlang's own in-memory database system, which is used by many to store shared data in parallel applications. Using ETS concurrently is a challenge, and even the Erlang/OTP R14B release notes claim that certain uses of it ""will never scale"". How to do it in a way that might work, and how much truth there is in this claim will be topics in this talk.
Understanding the effects of ETS concurrency options, and how they reflect in the underlying implementation is required to see the limits of ETS scalability, but also the opportunities. Using the ets module's interface properly is required to get good performance even on future releases of Erlang/OTP. 

Talk objectives: The talk will give insights about when ETS will scale well and when it will scale badly when used in parallel programs.

Target audience: Developers of parallel Erlang applications.
