Projection for correlated events

Hi

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: -

https://eventstore.org/docs/server/4.0.1/metadata-and-reserved-names

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 https://eventstore.org/blog/20130227/projections-6-an-indexing-use-case

Many thanks

Jonny

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