Up to you: you’re going to be able to configure what works locally vs what works with the cloud environment. So for example, you could configure all read functionality (incoming traffic, DB reads) to work with the cloud, and all write functionality to work locally.
Further down the line, we’re planning to support Copy On Write for databases - so you’d read from the cloud, write locally, then read the records you wrote locally (and records you haven’t written, from the cloud).
Disclaimer: we’re still pretty early in the roadmap, so currently only support mirroring incoming traffic. But we’re moving fast :)
Yes! This is actually in development at the moment so should be out really soon. Along that same line, we're also planning to support routing of outgoing traffic back to the cloud environment. We're obviously thinking of both those features as more suitable for use with a staging environment rather than production.
