[00:35:52] <gsd> if im connecting to multiple hosts, do i need to prepend user@pass: to each host in the connection string
[00:45:47] <sheki> hey i have a query which looks like { a : "some string", b : {$gt : new Date(1393229650673)}} =>
[01:57:59] <ben2> hey all, I have a collection of users with many fields I need to filter by. I want to select data from a log collection that belongs only to the subset of users I filtered by. Some filters can return 100k users which seems like a lot of data to send back and forth if I were to first select all the user_ids (all 100k) and use that to filter log data. Is there a better way to handle this?
[02:47:19] <the8thbit> I'm having trouble connecting to my mongodb on an openshift account. When I ssh in and try to enter the mongo shell I get:
[02:47:20] <the8thbit> Thu Mar 6 21:32:01.272 Error: 18 { code: 18, ok: 0.0, errmsg: "auth fails" } at src/mongo/shell/db.js:228
[03:13:22] <the8thbit> joannac: I'm also getting an error any time I try to do a get query, so if all I need to do is supply credentials there then I dont think the issues are related
[03:18:14] <the8thbit> joannac: readOnly is false for admin, is that what I'm looking for, or is there more somewhere else?
[03:23:48] <the8thbit> is pwd the field for password? Because it wasn't what it was supposed to be, but I assume its salted?
[03:24:44] <joannac> add a new user and use the new-style of users: http://docs.mongodb.org/manual/reference/method/db.addUser/
[03:29:36] <the8thbit> joannac: So when I check my collections, I notice that I don't have the same collections that I do when I test locally
[03:31:00] <the8thbit> on the local one I don't have any db users and the users collection is a collection I made for holding users of the application
[03:34:48] <the8thbit> joannac: Right, I know. Locally, I don't have a system.users because I don't have any db users
[03:35:19] <the8thbit> remotely I have db users, but I don't have the users db that I'm using to manage users... which is why I think I'm getting that error when I try to log in
[03:36:32] <the8thbit> but I think the reason I'm getting an error is because the app users collection doesn't exist
[03:37:09] <the8thbit> joannac: Well, I'm confused because I have it locally, its just not showing up remotely
[05:40:40] <brucelee> for mongodb + ssl, can we simply compile the source to install it, and then the just save the produced folder to subsequent servers
[06:41:35] <scruz> hello. been trying to do this https://dpaste.de/o6dw with the aggregation framework. any help, please?
[07:20:56] <scruz> kali: just found http://www.kamsky.org/1/post/2013/04/using-aggregation-framework-to-reshape-schema.html
[11:06:24] <danpalmer> I'm doing a research project at uni, analysing MongoDB in terms of distributed systems, I was wondering if some people here could give me some input.
[11:07:30] <danpalmer> I'm trying to figure out Replica Sets and leader elections stuff. There doesn't seem to be an algorithm like Paxos/Raft/etc behind it, and I can't get much detail on how things like partial network failures and latency are handled.
[11:08:46] <danpalmer> Is it the desire for the sort of 'tunable' consistency in MongoDB that decided that? Those consensus algorithms are typically used for distributed transactions.
[12:18:44] <GHJGH> afternoon all, how do you go about naming your mongo servers? ive come up with - {env}-{service}-mdb-{replica-set}-s{#shard}-{#server}, is there a better way?
[12:21:18] <kees_> i gave them names from greek mythology and remember what it does, but if you want to use those names, don't user abbr too much
[13:23:03] <NoReflex> I only have a "paste" of the actual binary data from a logfile; I cannot access the mongodb instance where the actual binary data is stored
[15:25:12] <obihann> with the following model, how would I perform a find a populate on the members.user object? https://gist.github.com/anonymous/9413322
[15:55:38] <Veejay> Is there a command that allows one to retrieve the URL of the primary node in a replica set?
[16:43:35] <freeMind> Hi every body, im using mongoDB with c++ driver i want to get list of filed names of each document in my collection if u can help me
[17:03:39] <codydh> Hello! Silly question, but if I apt-get install mongodb on Ubuntu, how do I figure out the necessary user/pass to connect using a local Node.JS app?
[17:25:20] <chandru_in> If the page of index to be updated is not in memory, will mongod yield the lock while fetching the page?
[17:25:52] <nukulb> joannac: quick question for you when you get a minute. on the text search docs - http://docs.mongodb.org/manual/tutorial/enable-text-search/ it say its Beta feature and don't enable it on Production. What are the consequences of using this in Production?
[18:31:20] <joannac> nukulb: the same as any other beta feature? it may not work, it may have bugs, it may have effects you don't expect, the implementation details (e.g. API) might change
[18:32:43] <nukulb> joannac: is there a timeline for something like this to come out of Beta and become a full feature? doesn't have to be accurate just looking at it so I can plan better to switch over to this
[18:36:03] <nukulb> joannac: more importantly I am looking for a way to do a weight search other than using a full text search. So basically be able to do a search using $regex with different properties get different weights and then sort by that . Do you know of any examples?
[19:34:48] <avelino> hi guys, 'm working in open source BI application, per default used riak, the monongodb team want to sponsor to implementation mongodb alternative data base?
[19:46:50] <tscanausa> everytime I try to use ip addresses as replica set configs it says cant find self in initialize
[19:50:44] <joannac> okay, on one of your secondaries, pastebin: rs.conf(), rs.status(), a log snippet, and mongo --host ipaddress --port port
[20:10:33] <joannac> tscanausa: i have seen this work, so I really need more information to figure out why it's not working for you
[20:20:04] <tscanausa> joannac: here is what I am currently seeing https://gist.github.com/anonymous/9419116
[20:30:38] <joannac> tscanausa: also, you're on a very old version of mongodb which means you may be hitting a bug I'm not familiar with
[20:33:11] <mboman> I was thinking of plotting some values from my mongodb collection, what would be the best way to do this? Own python program, or has something already been created?
[21:54:34] <harttho> Say you want to store X documents a day (where X > 10mm and is distributed over the day), the order of the documents doesn't matter, but querying them on time_entered (separate than _id) is important
[21:56:43] <harttho> Originally we had a separate collections by day, but querying can get annoying having them separated
[22:12:33] <synth_> hello, i'm curious what the best method for checking if a record in a collection contains an attribute?
[22:14:21] <synth_> okay, so in python, i tried doing this, however i'm not sure if i was doing it correctly.... here's my code: self._user_collection.find({"uid":uid}, {attr:{"$exists":True}}); where "attr" is an attribute like "phone"... using that code, i was still able to return a cursor even though the attr didn't exist
[22:32:59] <iksik_> hello, it's my first time with mongorestore https://gist.github.com/krzysztofantczak/6e8b07223abee3743356 - but there is one weird thing, api collection is empty after restore, any ideas why?
[22:37:00] <iksik_> i was also trying to copy this one collection using robomongo tool with exactly same result, all collections are fine but 'api' is empty :|
[22:38:47] <iksik_> example document from 'api' collection looks like this https://gist.github.com/krzysztofantczak/9814af36141d1cb2812f - if it matters
[22:42:48] <synth_> any idea why i'm getting this error? self._user_collection.find({"uid":user_id}, {"phone":{"$exists": False}}) produces: pymongo.errors.OperationFailure: database error: Unsupported projection option: $exists
[22:43:46] <cheeser> that second document is for the fields to return from the documents the query matches
