Disable Relevance
Available from 10.0 GA and onwards
If for some reason, you need to disable relevance in production for visitors (http requests) you can set the following property:
/targeting:targeting: /targeting:disabled: true
Available from 12.0 GA and onwards
If you want to disable the visits aggregator and model training (see Experiments and Trends Dataflow) for a specific cluster node (for example you don't want the frontend delivery nodes to do the data crunching) , you can do this by specifying the system property
targeting.dataflow.service.disabled: true
