Events not projected in order?

[slashdotdash]

The order of events in a stream is determined by the stream_version column in the stream_events table. You can run the following SQL query for a given stream id to get ordered events. Stream id 0 is the global “all events” stream.

A Commanded event handler is guaranteed to receive events in the order they appear in the stream. An Ecto projector is just a specialised Commanded event handler.

If you can create a code sample to reproduce the issue you are seeing I will take a look.

Thank you for this @slashdotdash ! It's good to know the guarantee.

Not sure which stream the projector runs on, but either way, joined w/ stream_events and ordered by stream_version, it still is the correct order:

Will dig a bit more and if that does not help will try to create some code to reproduce.

Ok, this must have been my fault. I can't reproduce and its gone. Rebuilt the projection from scratch, first time exploded again, second time runs smoothly now, probably all the way through to the end.

Reason was probably some unclean state while developing the projector or some unclean state was produced when shutting down the development Elixir process while projecting (CTRL+\) and upon continue it exploded then..

However, this is not a bug in this project. Closing this issue. Thanks for your help!
