Redis is just the start.
There will be more FIP for TCP in general. And more specific rules for certain protocols atop of it, like HTTP, C* and others.
I'm the author of RedFI, it's part of an ongoing initiative to create an open-source platform for fault injection, in a staging area. Also to make it part of the Continuous Integration process.
So this is just the start.
I would love to get your feedback!
