Great job! I played with RxJS and it's so useful in some cases. I'm sure RxDB will also help us a lot.

I have some questions:

1) How much storage space can we use? 2) How fast will it work? I uderstand that it's async, so I guess that browser scripts won't be blocked. 3) Are there any known limitations? Is it production ready?

1. Storage-Limit depends on which browser you use it, see https://pouchdb.com/faq.html#data_limits In other environments, storage is unlimited.

2. No, browser-scripts will not be blocked. It works quite fast. The speed depends on which storage-adapter you use. In browsers for example its slower with localstorage compared to leveldb in nodejs as storage-adapter.

3. Yes its production ready.

Good to know. Thanks.

What is the primary storage used? localStorage?

It's based on the ecosystem of leveldown-adapters. Therefore you can switch arround the adapter to use RxDB in different environnements.

There are adapters for indexedDB, localstorage, websql, filesystem and many more.
