[00:33:11] <eka> hi all... have a sharding setup with lotsa traffic/data, but with 1 mongos, could be that the bottleneck? Have many app servers requesting to that mongos at a high rate, thinking on adding 1 mongos for each app server

[06:01:37] <ttdevelop> hello

[06:01:56] <ttdevelop> is there a way to only return a part of a collection that match the condition

[18:37:17] <roxlu> hi guys

[18:37:29] <roxlu> When I want to connect to a mongodb do I need boost?

[18:38:02] <wereHamster> no

[18:38:11] <roxlu> ah great : )

[18:38:29] <roxlu> (I'm using c++ / c )

[18:38:35] <wereHamster> you need the syscalls socket(), connect() and write()

[18:38:39] <wereHamster> everything else is optional

[18:38:45] <wereHamster> read() as well

[18:43:13] <roxlu> wereHamster: the docs say ths: The C++ driver requires the pcre and boost libraries (with headers) to compile.

[18:45:58] <wereHamster> well, this is the first time you mention that you use the C++ driver..

[18:46:20] <wereHamster> and if the docs say that you need it, then you need it.

[18:46:35] <roxlu> >> 20:01 < roxlu> (I'm using c++ / c )

[18:49:07] <roxlu> ah I'll go for the C lib

[18:49:10] <roxlu> nice and clena : )

[18:49:14] <roxlu> s/clena/clean

[19:01:41] <aboudreault> is it dump to keep all my users/groups/permissions in mongodb too ?

[19:03:31] <aboudreault> *dumb*

[19:28:06] <roxlu> wow

[19:28:36] <roxlu> mongodb is awesome! ... used a long time ago...but forgot how easy it is to manage data

[19:29:24] <kali> mongodb is love.

[19:29:29] <roxlu> :)

[19:29:51] <roxlu> nog sure if this is possible... but ...

[19:30:37] <roxlu> I'm receiving JSON objects like: { name:"somename", age:234, children:[{name:"name1"},{name:"name2"}]}

[19:30:54] <roxlu> would it by any change be possible to insert that directly?

[19:31:19] <kali> yes. mongoimport as a csv option

[19:31:28] <kali> and a json option too :)

[19:32:05] <roxlu> kali: and, if I want to insert only a part of the object?

[19:32:19] <roxlu> then I better create a bson object from it, and remove what I don't want?

[19:32:54] <kali> or parse the json with whatever your conmfortable with nd push to mongodb directly

[19:33:47] <roxlu> yeah I'm using a light weight json parser now, and storing it into a bson obj

[19:34:13] <kali> if you want to stick to shell, there is http://kmkeen.com/jshon/

[19:36:24] <roxlu> are there other fast, tiny json parsers which are popular?

[19:37:31] <ttdevelop> i tried to directly import a json data in the form of [{},{}], it seems like for import to work with mongo, it needs to be in {}\n{} form

[19:39:11] <roxlu> ok

[19:39:41] <roxlu> when I'm inserting millions of entries, do I need to be aware of something with using "bson_append_new_oid(..)" ?

[19:45:09] <rAad> I've got an $avg field in my aggregation engine pipeline. Is there a way to truncate the number of decimals returned (say, 2 decimals for monetary amounts)?

[19:48:50] <ttdevelop> anyone knows any good GUI tools to manage mongodb?

[20:30:31] <roxlu> how do I insert an array like: [0.5,0.1,0.6] ?

[20:30:46] <roxlu> into a bson object (using C)

[23:32:44] <wereHamster> boah, why did mongod preallocate 138 local.* files, each 2G?

[23:32:50] <wereHamster> isn't that a bit overkill?

[23:33:30] <wereHamster> uhm.. creating replication oplog of size: 279002MB. That's 280G?!?
