In my Sitecore 8.2 installation, i have the following tasks:
+---sitecore
| \---system
| \---Tasks
| \---Schedules
| \---Content Testing
| \---Calculate Statistical Relvancy
| \---Rebuild Suggested Tests Index
| \---Suspend Corrupted Tests
| \---Try Finish Test
Since i use Solr for indexing, i'm pretty confident that the Rebuild Suggested Test Index
should only trigger on the Authoring environment and therefore needs to be set to Never Publish
. Does anybody know whether this needs to be done for the other 3 tasks as well? Or does every Delivery server in a scaled environment need to run those 3 tasks?
