Resubmission of Events

Robert

I just wanted to understand how others handle the resend requirement with solace.

Following Use Cases where you need to resend some events:

• Initial Load (multi instance system and new system requires some data)
  => send all data from object store to new instance (do not impact others)

• Resend some events for certain period of time
  => send time filtered events to one specific subscriber

Here my thoughts:

Pros:

• Re-uses the existing filters each subscriber defined to filter into the customer queue
• Clone on CI/CD which creates Queue and Subsription to clone each topic by replacing "ALL" (2nd position) with subscriber system name in this case SYS1

Cons:

• Confusing why on pub sub the target (which normally should not be known) should
  be part of the topic name.

Pros:

• Direct push to subscriber queue (as resend is intended just to 1 subscriber) as no impact to others should exists

Cons:

• Loosing the subscription filters between queue and topic
  Workaround: Read out the filters set and apply these topics to filter out the
  matching topics from event store.
