Changefeed process events from the day that is specified

[florimm]

Hi
Im trying to add new projection to an exisitng project (sample from eventsourcing from this repo) and my assumption was that if I set StartTime (let say DateTime.MinValue.ToUniversalTime()) on ChangeFeedMonitoring when I configure ProjectionStore and register a new EvetItemProjection then projection should be executed for the new EventItemProjection even that the new projection is behind the others. I only see that in Lease container new items are register for the new ProcessorName that I did add but the new projection is not projected at all. What Im doing wrong or is this possible to be done?
Thanks in advance.

I'm not as familiar with the change feed source, unfortunately, that area was contributed by @mumby0168 - hoping he can help here. Sorry for the delay, been buried lately...

@florimm If I'm understanding you correctly, you have an existing change feed, made a change and set StartTime.

Short answer is, that isn't how StartTime works and this can't be done. (At least the way you want)

Longer answer is StartTime is only used when the lease for the change feed does not exist, so only on initial startup. Once the lease is established, it only moves forward. You would have to either delete the lease for that process or change the name of the processor (it would create a new lease). This would reprocess every record in the container. I'm not exactly sure how that would react with event sourcing. I don't use the event sourcing library, so don't have a work around for you either.
