I'm working on the Drupal 8 multisite where there is main site and partner sites.
For example partners publish events or news.
I want some content from partner sites to be available on the main site. How can this be done?
What I discovered so far:
sharing db tables seems tricky - there are just to many node tables and their dependencies will likely break.
I could create custom entity but then its not place in "content" (beacause it's not node type) and I will lose nice content handling. but tables are easier to share then.
I could copy the content but then i have copies not the same content (what are possibilities here?)
