@fehmicansaglam
It means reactive in Turkish
It is read as it is written, if it means anything to you:)
Mike Limansky
@limansky
And where should I put the stress?
I'm asking, because I'm going to mention it in my speech at Scaladays.
Fehmi Can Sağlam
@fehmicansaglam
Cool:) actually google translate application pronounces it correctly. It has 2 syllables. Tep-kin. Does it help?
And could share the name of your presentation?
Mike Limansky
@limansky
yep, it helps. thanks
so, I will say a little about existing solutions for MongoDB in Scala, and why I started to develop MongoQuery, before cover the implementation details.
Fehmi Can Sağlam
@fehmicansaglam
Will you mention about Tepkin in a good way or not?:)
Mike Limansky
@limansky
In the way that it not supported in mongoquery yet :-D
Fehmi Can Sağlam
@fehmicansaglam
Haha:)
Mike Limansky
@limansky
but I'm thinking on it :)
Fehmi Can Sağlam
@fehmicansaglam
Good news. Good luck for your presentation
Mike Limansky
@limansky
thanks
the problem is that I didn't find the way to construct BsonDocument in macro from the List[(String, Any)].
Fehmi Can Sağlam
@fehmicansaglam
Hmm
Fehmi Can Sağlam
@fehmicansaglam
I will come up with a working gist soon
Mike Limansky
@limansky
thanx
Fehmi Can Sağlam
@fehmicansaglam
@limansky i have updated 0.5-SNAPSHOT
    val elements: List[(String, Any)] = List("name" -> "name", "age" -> 3, "salary" -> 4.0)
    val document: BsonDocument = BsonDocument.from(elements)
you can construct a BsonDocument from (String, Any) tuples like above.
Mike Limansky
@limansky
@fehmicansaglam Great! Thanx. I'll try to use it this evening :+1:
Harmeet Singh(Taara)
@harmeetsingh0013
@fehmicansaglam is there discussion room for #reactivemongo-extensions ?
Fehmi Can Sağlam
@fehmicansaglam
Nope
Harmeet Singh(Taara)
@harmeetsingh0013
i have litte probem with query dsl
if you allow, i can paste the link of my query here ?
Fehmi Can Sağlam
@fehmicansaglam
Pleas file an issue on github
Or you can ask in the reactivemongo google group
This room is just for tepkin
Harmeet Singh(Taara)
@harmeetsingh0013
ok @fehmicansaglam , paste the issue on githum abd google group
that's why, i taken the permission from you
Fehmi Can Sağlam
@fehmicansaglam
ok, i have posted the answer to SO.
Fehmi Can Sağlam
@fehmicansaglam
If anyone is interested I have opened a room for my new project: elastic-streams https://gitter.im/fehmicansaglam/elastic-streams
I am trying to come up with an implementation of reactive streams for elasticsearch

hey @fehmicansaglam . Sorry that it took so long to report back. The collection sink api looks just as expected. very nice, thank you. I had no luck yet running this in a combined example (like having a flow stdin->collection.sink ; collection.find(tailable=true) -> stdout) but I'll give you a link once its running. might be a nice example.
Daniel Wegener
@danielwegener
I am still wondering if one could make the collection.find() returning directly a Source instead of returning a Future[Source]. In the case when the future would fail, you could just let the stream itself fail directly. This could enable the use of stream supervision for recoverable failures (like when the mongo is not available during flow materialization, recover with a restart). In the end, Sources are easier to compose.
Fehmi Can Sağlam
@fehmicansaglam
@danielwegener I have changed Future[Source] return values to Source and updated 0.5-SNAPSHOT
I agree that it is easier to use the api right now
Daniel Wegener
@danielwegener
Again, cheers, @fehmicansaglam, that was awesome quick.
Daniel Wegener
@danielwegener
Mhm weird. Sink seems to work fine but the MongoCursor seem to receive a reply with a cursorId 0 (as of documentation that states that indicates a dead cursor, whatever that means) and thus eagerly closes the stream. Would you be fine if I'd add ResponseFlags to the reply class?
Fehmi Can Sağlam
@fehmicansaglam
@danielwegener as you said if no documents match the query(or the collection is empty) cursor is dead. If you add at least 1 document to the capped collection everything works fine. I couldn't find much in the documentation so I left it as it is.
What do you mean by ResponseFlags? Could you point me to the documentation?
Daniel Wegener
@danielwegener
The response flags are documented in http://docs.mongodb.org/meta-driver/latest/legacy/mongodb-wire-protocol/#op-reply . They already a field flags in https://github.com/fehmicansaglam/tepkin/blob/master/tepkin/src/main/scala/net/fehmicansaglam/tepkin/protocol/message/Reply.scala but are not parsed (but maybe I am in the wrong version of the wire protocol).
I think I have misunderstood the tailable cursors then. But why would the mongo give me a dead cursor for a tailable cursor query on an empty collection if I want to query all elements that will arrive there in the near future. I thought that is what tailable cursors / capped collections are made for.
Fehmi Can Sağlam
@fehmicansaglam
I also think like that. We may look at the official driver's source code or ReactiveMongo
Maybe there is a way to handle empty collections
Daniel Wegener
@danielwegener
I will try to tail query a non empty collection this evening and report back then
Fehmi Can Sağlam
@fehmicansaglam
BTW it will be great if you can send a PR for flags
Daniel Wegener
@danielwegener
Wip :)
