Didn't have a good experience with them. One day we suddenly started to experience severe latency spikes, lasting for more than a day, causing timeouts. Unrelated to our DB which was small, even happened on trivial queries - a networking thing on their side. Google showed this to have happened before with certain regions of theirs. If you can't offer a certain region in a stable manner as a DB vendor, don't offer it. The whole point of outsourcing DB mangement is to take care of these things.
Huh. That sucks but also isn’t surprising. Seems like putting this in the cloud eliminates most of its benefits though. If you’re going to wait for that much latency you might as well use a “real” (traditional big complicated) rdbms.
For me, a lot of the draw is that it's cheaper than managed db services for small/toy projects of mine (that I don't want to use dynamo db for) - that and in a previous job it was useful as relatively temporary multi-tenant storage.
