Redis sentinel[0] is the HA solution for redis for quite some time.

I haven't heard good things about Redis Sentinel nor am I sure of their failure modes, which is why I wouldn't describe it as decent.

I haven't kept up to date on "Sentinel 2" that was launched with 3.0 so the situation might have changed.
