Is there a webpage that says what segments and stores we can remove from your production aem servers? I want to get rid of the contexthub.commerce stores and the default segments.
For ContextHub configuration information -- see the following AEM docs:
Hope this helps.
You can remove any and every store as long as you are not using that. There is no restriction or mandatory store components.
Though few are good to have store like Resolved Segments Store and Campaign Store.
