API For Adding Messages Without Loading Entire Stream

[warappa]

I have a constantly growing stream to which I just append messages. I don't need the entire stream, but currently the only 3 options I have are the following:

• use Store.OpenStream:
  Loads whole stream (with deserializing,...) and append the new messages. Not performant, not memory-friendly
• use snapshots:
  Snapshots are planned(?) to be deprecated in the future.
  Also: why load a big snapshot if you just want to add 1-n messages?
• Use Store.Advanced.GetFrom(streamName,0, Int32.MaxValue):
  Use Store.Advanced.GetFrom(...).LastOrDefault() to get the latest StreamRevision and CommitSequence and prepare a CommitAttempt.
  Still loads the whole stream.

Greg Youngs eventstore has the ability to just append a message: EventStoreTransaction.WriteAsync(...) - an API like this would be great!

You're not the only one requesting this feature. I think snapshots are currently the best work around.

I've bodged this with an empty snapshot object every 10 commits - yuck!

+1 for this feature. Opening a stream for append-only sounds like a natural idea. Any specific reason why it's not implemented?
