here we need an if statement to skip not enabled backends. See https://github.com/metal-stack/metal-roles/pull/310/files#diff-81777600d83d4794dafee8e817a4b696b9c1a05fe38798329235b2ec72537cd1R229

I would prefer to remove the support for meilisearch completely instead of adding the complexity of supporting multiple auditing backends

Maybe we will have introduce multiple backends though if FI-TS wants to have Splunk connected. But maybe also we want to introduce the buffer service as well, which we were discussing as well.

in my opinion, metal-api should only have one auditing implementation, if other parties are interested in other auditing backends, then this should be solved at a later layer.
This is why i would like to vote for a dedicated auditing backend which has plug-able backends

I also think this should be done but it comes with quite a lot of work and maybe it's acceptable to introduce this beforehand and then switch to the dedicated auditing layer because in production we see too many issues with Meilisearch currently. :(

I could live with small steps towards the final solution as well

Is there there some documentation about this behavior of only using the first auditing backend as source for the search?

Not yet... also not sure if it's correct to do this. Probably this should be somehow configurable.
