[EventStore.Client] How to retrieve current state of a projection which runs "foreachStream"?

Hi!

How to retrieve the current state of a projection via the EventStore.Client API if the projection runs “foreachStream”?
The only way I’ve found so far is ProjectionManager.GetState() which does not have a stream parameter.

Hi,

Can you post your projection? What are you trying to achieve?

cheers

I want to achieve exactly what is shown at http://codeofrob.com/entries/creating-a-projection-per-stream-in-the-eventstore.html

However, I cannot find the correct ProjectionManager method call to get the state of such an per-stream-projection, calling GetState(projectionName, credentials) returns nothing - of course - because it loads */projection/myprojection *and not /projection/myprojection?partition=STREAM

So what’s the way to go?

Best regards,

It’s quite possible that projections manager was never updated to allow that. I’ll open an issue on GitHub. Can you confirm that get with partition=stream works?

Yup, http://localhost:2113/projection/MyProjection/state?partition=MyStream1 does work just fine, it returns the per-stream-state as JSON.

Is the .NET Client API and with it the ProjectionsManager somehow outdated or otherwise not ready to use?

Best regards,
