catchupSubscription - LiveStarted question

[Steven Blair]

Take this code:

var catchUpSubscriptionSettings = new CatchUpSubscriptionSettings(1, 500, true, true,"CatchupTest");


eventStoreConnection.SubscribeToStreamFrom("myStream",
                                           -1,
                                           CatchUpSubscriptionSettings.Default
                                           (e,r) => {
                                            //Event Appeared
                                           },
                                           (eventStoreCatchUpSubscription) =>{
                                            //LiveStarted
                                           }
                                           ,
                                           () =>{
                                            //Subscription dropped
                                           });

Since we have instructed EventStore to read 500 events at a time, would the following be true:

1. EventStore reads a stream containing 500 or less

2. EventAppeared starts handling these events

3. Almost instantly, liveStarted would be fired ebcause EventStore *thinks* it's at the end of the stream

I appreciate this may well be by design, but just wanting to understand.

An issue we might have is, the last batch of 500 gets read, and a problem occurs, but we signal that LiveStarted

Maybe it's more a self amde problem here. My understanding was LiveStarted was a signal to say "All your catchup events have been procssed by EventAppeared"
