Sorry I did not see this reply sooner!

1. Yes Ditto uses query-based sync. Candidly, the flexible sync in Atlas has roots back to when I was VP of Product at Realm. It was a must for me, but I think got abandoned for performance issues then brought back. Ditto was built always to support flexible/query sync. We recently have added our own more advanced query engine - DQL (SQLish) and it will enable JOINs and other advanced queries while still being schemaless JSON collections. In this regard Ditto is a better compliment to Mongo than Realm is from data model perspective.

2. Yes this partner-first approach is huge opportunity for us. Given Realm had to sell, we were very focused on building a sustainable business. This meant though more focus on enterprise and specific use-cases than going wide to all developers (you can see how well that worked with Firebase, Parse, and many other developer products when you have VC backing). This means we have a solid foundation technically (large-scale deployments in mission critical systems) to now handle wider awareness. Mongo will really help us bring the awareness of Ditto.

3. Right now candidly our permission system is nascent compared to Atlas - a webhook fires from Ditto to allow you to integrate into external identity systems and apply permissions. The focus with enterprise meant we targeted use-cases that didn't have too much dynamism in their permissions and data models, so you will find our system naive comparatively. This is a top priority where we will be adding built-in dynamic permission functionality that is similar to Device Sync later this year.
