I’m interested in using FME Flow for Connection Storage in FME Workbench.

We have a single FME Flow instance that does not have redundancy. I’m concerned that if Flow is unavailable, that FME Workbench will effectively also be rendered unusable if I use Flow for connection storage, based on what I’ve read in the documentation.

Further, FME Form provides me a sort of redundancy at the moment - if Flow is unavailable or if the engines are consumed, I can run my processes locally, as a last resort. In my understanding, moving my connections to Flow would remove this redundancy and leave me more vulnerable to network/infrastructure/system issues.

If the above is true, would it be possible to maintain a local cache of connections, similar to the default Personal Database Connection Storage, where it prompts for and perhaps even requires connection and syncing to Flow, but has some sort of fail-back mechanism in the event of failure?

I could keep an export of connections locally, or a Shared Database copy, but this will go stale and defeats the purpose of the FME Flow option, I imagine.

Thanks for any thoughts or corrections on the above.

Hi ​@phoeffler , what you're describing—a local encrypted cache that syncs with Flow and falls back gracefully when it's unreachable—is a great idea. It maps closely to internal work we're tracking on rethinking connection management (which includes local caching for remote storage), and I've linked this idea posting there. We don’t have any established timeline for that (nor is it particularly high up in our backlog), so thank you for creating this idea to gauge wider interest within the FME Community.

One question that may become relevant if this is selected for development work: would you expect offline mode to be read-only, or allow edits with later conflict resolution?
