I don't think CockroachDB will be a good fit for your application. The nodes expect constant network connectivity, they're talking to each other every few milliseconds. You want a very fast and reliable network. For logging, some sort of store and forward architecture may be better. I don't think the level of consistency provided by CockroachDB would be necessary.
