This is something we are currently building at Klarrio on top of YugabyteDB. We have opted for YugabyteDB table spaces to solve the isolation problem. We allocate a number of dedicated tablet servers to a tenant so that their db objects are close to each other. YugabyteDB executes queries only on those tablet servers where the data relevant to the query is. A resource heavy tenant doesn’t have an impact on other tenants. It’s not really “serverless” but does seem to solve the problem at a cost. Tenants receive complete databases with grant permissions so they can do as they please. Because YugabyteDB uses Postgres 11 under the hood, we have an additional sanity layer in form of a Postgres process utility hook which prevents the tenant from escaping the sandbox. |
