A task for a long night, but I hope when I turn on the coffee machine tomorrow morning (or afternoon) I will be done with an example that everyone can run locally.
Please don't do that. We all (?) know that Elastic can't be used to mine BTC. It's not 2009. Even alts for Elastic will be a big problem. This will only show weaknesses of Elastic, nothing more. We should say firmly to everyone that Elastic can't be used to mine BTC. We are building false conviction here. Please @EK, focus on serious things.
As a first little showcase, why not. The real "killer-app" will be scientific uses cases.
