I'm very excited about this! Without reading too much into this, is it safe to say it's like a self-hosted firebase?

"Due to the way deepstream structures its data (JSON blobs, identified by a primary key) it is recommendable to use an Object oriented or schema-less database (e.g. MongoDB or RethinkDB), rather than a relational database like MySQL."

Is there a way to run complex queries against the data or it designed to abstract that all away from you to be as fast as possible?

Yup,the data is still queryable.here's an article on the subject http://deepstream.io/tutorials/searching-and-querying.html

Interesting. How does it differ from https://getstream.io ?

The GetStream server isn't open source, is it?

I believe they Open Sourced a significant part of it here - https://github.com/tschellenbach/Stream-Framework

Very necessary. A few questions:

- How big can records be? Are they stored as a single object in the persistence layer or using something like materialized paths. The firebase data model is one huge JSON structure, so this looks different.

- How are conflicts handled? Last writer on server wins or last writer anywhere? Do you ensure eventual consistency of all the clients even when you apply optimistic writes on the client?

- Can data be larger than the cache size? How is cache eviction handled?

Similarly (without reading too much about it) can I use InfluxDb instead of RethinkDb? (Disclaimer: I'm a RethinkDB fanboy, but I'd like to know my options.)

InfluxDB is a time series database (think reporting/analysis of collected system metrics). It's not intended as a general purpose database.
