joola/joola

Embedded, realtime data analytics and visualization.

You'll notice that Joola starts twice, this is because during the first run MongoDB wasn't available, but the restart flag kicked in and it tried again and stayed up after MongoDB became available.

Also, you'll notice that I've used -p 222:22, this allows you to connect to the machine while it's running and get the logs for review. Here's an example:

itay@joola01:~$ ssh joola@localhost -p 222

The password for joola is joola.

Let me know how it goes :)

@itayw

great news, the coming merge of #673 will allow joola to run without a stack, i.e. no need for redis/mongo/rbq etc... Only if you need to scale up and support multiple nodes you'll need to configure these additional sources.

Ivan Hamer

@ihamer

It works! Great. I really appreciate such a quick response, Itay.
Also, great work to make it standalone.

Itay Weinberger

@itayw

@ihamer my pleasure, let me know if I can help further. I expect to complete docs, especially the needed SDK ones by the first week of March.

@itayw Still waiting for OAuth instead of the current auth implementation...

Itay Weinberger

@itayw

hi @thedrow, yeah, sorry it dropped below radar. One thing I did struggle with is identifying how the OAuth part should work in combination with Joola. I must admit that I'm a bit lacking in this field.

Itay Weinberger

@itayw

I just merged #661 into the develop branch. Joola can now be executed without any stack, send me your feedback :)

Omer Katz

@thedrow

@itayw Hi, so OAuth can be either used as a standalone auth mechanism or in order to integrate with other systems

For example, if I have my own SaaS which uses Joola I'd like to reuse the same OAuth token to identify the user both on Joola and on my app

It also means that your API will use a standard mechanism for authentication which makes implementing clients much easier

Itay Weinberger

@itayw

I just merged #661 into the develop branch. Joola can now be executed without any stack, send me your feedback :)

Omer Katz

@thedrow

@itayw If you have more questions I'd be happy to assist

Itay Weinberger

@itayw

@thedrow what would the flow for your SaaS example? who's generating the token and how does the exchange actually works in the setup you have in mind?

Omer Katz

@thedrow

The Authorization server generates the token

It can be Joola or someone else

Itay Weinberger

@itayw

@thedrow to be honest I think would be good to incorporate it into joola but i'm a bit fuzzy on the actual flow.

Omer Katz

@thedrow

See https://tools.ietf.org/html/rfc6749#section-2.3.1

You provide a client id and secret key and get a token and a refresh token in exchange

Itay Weinberger

@itayw

checking....

Omer Katz

@thedrow

The whole idea is to be able to delegate the authentication and permissions to another service that already knows what a user can or can't view or edit

Itay Weinberger

@itayw

welcome @learnsomuch, feel free to ask questions :)

@Shumkov

Hello! For first, Joola is very similar that we are design now for internal analytics :)

We are think about move to trash our diagrams and start to using your great product!

Ivan Shumkov

@Shumkov

Can i ask you few questions to understand that?

Ivan Shumkov

@Shumkov

What's mean - "However, please note that Joola does not support query filters over arrays."?
I can't filter by array field?

For example:
i have interesets array field that contain ID's of user interests 1, 2 and 3.
Can i query users with 1 and 2 interests' IDs?

Itay Weinberger

@itayw

Hi @shumkov, I'm happy to hear you like Joola :)

With regards to in array queries, we have limited support, but I need to look into it and see how we can achieve your speicifc requirements.

I'll give it some tests tomorrow and let you know what I find.

Itay Weinberger

@itayw

@Shumkov I opened a ticket for adding tests, if you wish to follow it:joola/joola#700

Ivan Shumkov

@Shumkov

Thanks

I saw elasticsearch store adapter and i'm cunfused

For each insert you try to create index. Two query per one document.

Why did you not using bulk insert?

Did you use elasticsearch store in production with big data?

Itay Weinberger

@itayw

Were using

We're using mongo in production, the elastic plugin is still under heavy development

There are several performance/efficiency issues with the plugin at the moment. For example each insert also calls for an index refresh which is not performance friendly.

Ivan Shumkov

@Shumkov

Yes, i told you the same.

Itay Weinberger

@itayw

@Shumkov i've worked on the es plugin and took care of some of the major issues. In addition I've added examples to #700 showing in-array queries. It's not stable yet and I do expect to apply several additional changes to the plugin, but let me know what you think. Builds are now running through travis, so make sure you try out develop branch. If you want I can also push a pre-release to npm.
