Projection for correlated events


I am using EventStore version 4.0.1. The start params I’m using are: -

–run-projections=all --start-standard-projections=true

From the following statement “Projections will honor both the correlationId and causationId patterns for any events it produces internally” in the documentation: -

Does this mean there are built-in streams that you can use to get back all correlated events (in the case of correlationId)? Or is it the case you need to create your own projection similar to the example in this blog post

Many thanks


You need to create your own, projections emits metadata with $correlationId and $causationId.
