Do you support any type of debugging in foxx, can I somehow set breakpoints and inspect the state? We're currently using Arango and it gets tedious to call foxx-manager replace every time I'm doing a change on the db

You can active the dev mode for a Foxx app. This way any change will be directly visible without the need of replace.

why do we need this? Mongo (3.4) is now doing graph and will also (obviously) do document and key-value. Is there something special about the storage engine, for example, that will make this awesome for range queries (contiguous location ala RIAK TS or Cassandra rows)? Does it optimize for the new SSD controllers that have order of magnitude higher random read throughputs? Does it leverage GPU RAM? Does it occupy some barren area of the CAP triangle?

Does it do something new, or is it just another neat query language on top of the same old storage algos? The "3-in-one" pitch doesn't fly for me unless the underlying storage tech does something special.

I'm an ArangoDB team member. The new graphLookup is far away to be a graph functionality. It's only a recursive lookup. Yes, the storage is special. The three data models are combined in one database core.

Looks like they were planning to Jepsen test later this year [0]. But it looks like they're preparing to run it themselves [1]? [0]: https://www.arangodb.com/2016/05/getting-closer-arangodb-3-0... [1]: https://github.com/arangodb/jepsen/commit/2b79809df73ca6c755...

Jepsen tests are basically a closure framework to conduct such tests. We took some of the existing test cases and rewrote them for ArangoDB. So these are not "official Jepsen tests" but tests we did ourselves to track down issues. If you want to inspect and retest yourself, that will be possible. There's no reason to keep the tests closed source. Of course it would be great to get ArangoDB Aphyr-approved eventually.

Until it goes under like RethinkDB and we are screwed. One should not use a non-established, open-source DB.

It takes time and money for an open-source DB to become established. I think Arango is taking the right steps and this investment will help a lot in getting there.

PS: I only started using ArangoDB recently for the first time on a client project and it was refreshing to say the least. Being able to do complex joins, coming from a Mongo environment feels so much better.
