yes they are database engines, but in many if not most of these cases there is only a single instance that is shared across all products at the company. it is very different than the rds model. of course there are access controls and abstractions such as schemas and tables but there aren't silos between data from different services
- closeparen 7y agoI guess neither of us want to out our employment history here, but for the ones I know about, that's absolutely not true. Reading from another service's database is sometimes possible but always considered hacky tech debt.
- jeffffff 7y agofrom what i've heard from reliable sources there are only 2 spanner clusters, one for ads and one for everything else. i'd be surprised if there isn't an isolated one for gcp but for internal google products there are only 2. i also have it on good authority that data sharing between services through edgestore and tao is common. i have less insight into the others.
