Hello,

I'm wondering, when a pipeline.workers is define either in logstash.yml and in pipelines.yml, which configuration is applied ?

I found out this setting was different in those 2 files.  
My guess would be that the pipelines.yml overrides the pipeline.workers setting of logstash.yml but I'm not sure at all.

Thanks in advance.

The value of `pipelines.yml` takes precedence over the value from `logstash.yml`, the value in `logstash.yml` will be use if there is no value for a setting in `pipelines.yml`, this is in the [documentation](https://www.elastic.co/guide/en/logstash/current/multiple-pipelines.html#multiple-pipelines)

> The value of a setting that is not explicitly set in the `pipelines.yml` file will fall back to the default specified in the `logstash.yml` [settings file](https://www.elastic.co/guide/en/logstash/current/logstash-settings-file.html).

So, if you set `pipeline.workers` in both, the value from `pipelines.yml` will be used, if you have multiple pipelines and one of them does not have the `pipeline.workers` setting, the `logstash.yml` value will be used.
