ArangoDB 3.0 Release – A Solid Ground to Scale

[hexalisk]

I would love to see a comparison between Arangodb and Rethinkdb, especially performance wise. Is it suitable for realtime applications? What language drivers are supported?

[don71]

Claudius from ArangoDB here. Frank already answered a question about realtime queries below: "We are evaluating various possibilities, how to implement streaming queries in an efficient and scalable way. For instance, are restrictions to the general AQL necessary for such queries to be able to scale? Stay tuned."

Regarding performance, it would be great if somebody with excellent knowledge about rethinkdb would contribute to https://github.com/weinberger/nosql-tests

Mad respect for these guys/gals, they managed to squeeze two game changing features in a single release: VPack and Clustering 2.0.

Not to blow my own trumpet but I think the new Foxx API (for letting you write your own HTTP endpoints in JS) is a huge step forward, too ;)

(I'm the lead developer of the new ArangoDB Foxx, AMA)

Great news! We decided a couple of months ago to go with arangoDB, we have built already a 32Gb Graph Database and so far it has performed really well. It's easy to install and great as a first contact on the GraphDB world aside from Neo4J.

This looks pretty fantastic! I'm going to give it a whirl at my company...except...

It apparently uses Facebook's RocksDB, which is also, I'm told, a pretty nice package. However, there is this:

https://github.com/facebook/rocksdb/blob/master/PATENTS

"The license granted hereunder will terminate, automatically and without notice, if you (or any of your subsidiaries, corporate affiliates or agents) initiate directly or indirectly, or take a direct financial interest in, any Patent Assertion: (i) against Facebook or any of its subsidiaries or corporate affiliates," ... and so on.

I think that means that if my company goes after (in any way, shape or fashion) any Facebook patents, and we're using ArangoDB, we're instantly in copyright violation.

Is this a roughly accurate assessment?

Thanks!

You don't lose your copyright license, you lose the patent grant. Most MIT/BSD licensed software doesn't come with a patent grant; many people assume that you get an implicit grant but that opinion will vary depending on which lawyer you talk to.

We have been using ArangoDB (2.8.x) for some time. Solid product with awesome support in Google group and SO. Great job guys! Looking forward to migrate to 3.x especially for the persistent index.

[overcast]

Awesome, I JUST started using ArangoDB for my latest project. So far so good, and these changes look solid. Only thing I wish they had(unless I'm missing something), is a GridFS type storage.

[janemanos]

Hi this is Jan2 from ArangoDB... my team mate Jan1 wrote a blogpost: You can already handle binary data with ArangoDB Foxx framework... here is how http://jsteemann.github.io/blog/2016/06/22/handling-binary-d...

[merqurio]

Pure curiosity, why do you miss GridFS? I think ArangoDB it already does that, back in time there was journal size setting, I'm not sure if it still has.

[sedlich]

Congratulations! What a nice bunch of new features. Thinking all three models from the ground up has really payed off! Will check out the docker image soon...

[neunhoef]

Max from ArangoDB here. Just to avoid disappointment: The official Docker image arangodb will need a few days to be updated and be validated by Docker. Use arangodb/arangodb:3.0.0 in the meantime.

Does ArangoDB support streaming queries like RethinkDB?

[fceller]

We are evaluating various possibilities, how to implement streaming queries in an efficient and scalable way. For instance, are restrictions to the general AQL necessary for such queries to be able to scale? Stay tuned.

[ralusek]

This looks really interesting. Is there a NodeJS ORM comparable to Mongoose for using Arango?

[fceller]

You can use the Foxx framework to create a REST api that suits your needs. There is also a community project for an ORM, see https://github.com/arangodb/arangojs/issues/215

However, in general it is more flexible and safer to use Foxx, because it allows you to fine tune complexes queries and supports transactions.

[continuational]

Can I change the number of shards on an existing collection without taking it offline?

[fceller]

Hi, I'm Frank from ArangoDB. You should create a number of shards that is much higher than your initial number of servers. ArangoDB can cope with multiple shards per server. This way, you can easily redistribute shards when adding new servers.

Is there a reliable python module for working with ArangoDB 3.0?

[merqurio]

We use joowani/python-arango, but I haven't test it with 3.0 yet.
