#mongodb logs for Tuesday the 9th of September, 2014
[00:30:32] <jekle> autoburger: you are good with mongo, just throw mysql out of the window. you won´t regret =P
[00:53:25] <jekle> autoburger: for me the biggest difference is that you need to think about what you want to accomplish at the very beginning to end up with a proper schema. there are no normal-forms like in sql databases.
[02:58:32] <classicc> In Mongoose, if how do I exclude certain properties from the resulting object on .save? eg. newUser.save(function(err, user) {... - exclude specified fields from the user object?
[03:31:09] <rfk_> any support for storing filesystem metadata in gridfs? or should i add the fields myself?
[04:21:34] <ome> With mgo, if I am scanning a query into a limit subset of the document attributes. Would that operation would be cheaper than scanning the document into a complete struct?
[04:44:51] <Boomtime> on the client it will certainly be cheaper, there is less data in the response to parse into native
[05:37:50] <Boomtime> your question was phrased entirely around the client, to which the answer is a definite yes, the client will have less work to do due to the less data it receives
[05:38:52] <Boomtime> the server-side is a bit more complicated; if you restrict the return fields to only those used by the index that services the query, then absolutely, the server will do less work - it can skip the document lookup and use the data contained in the index only
[05:39:38] <Boomtime> if the return subdocument contains fields not in the index, then the document has to be pulled into memory anyway
[05:40:16] <Boomtime> it can then return it all as is (it's BSON already, set to go) or it can reformat it the way you asked for
[05:41:40] <Boomtime> it is generally the case that restricting results to only include the fields you actually want is 99% of the time better off
[06:37:10] <Boomtime> @adil: i don't know PHP very well, but you should ask your question as somebody else here might
[06:38:47] <adil> $sColl = ScreenData::getCollection(); $sColl->remove( array('batchId' => $batchId), array('multiple' => true, 'j' => true, 'socketTimeoutMS' => -1) );
[06:42:57] <Boomtime> I was not aware you could pass socketTimeoutMS as a parameter at that level, but again, I don't know PHP
[06:43:45] <Boomtime> normally, you would set that in the connection-string, or other place at connection level
[07:27:43] <tuxtoti> Is there a mongo shell config file which gets loaded everytime you login to a mongo shell?
[07:53:50] <nEosAg> but while query on shell like db.coldata.find({object:6588}) it shows actual "✓" sign which is html representation of that code(✓)
[07:54:40] <nEosAg> so..does mongo do formatting while showing o/p on shell..i tried shell for viewing raw content of doc..
[07:57:39] <Eremiell> nEosAg: I believe, mongo stores everything in BSON, which is a binary format, so unless you can read ones and zeros, it needs to convert it back to JSON to show you.
[07:59:10] <Eremiell> but if you really really want to see the stored data, I guess, you can just cat the db storage files...
[08:00:23] <nEosAg_> Eremiell: so how can i know ..where is the mess..did code trying to insert that doc, has transformed that "code" to "html" ..
[08:01:37] <Eremiell> nEosAg_: whatever you get in mongo shell is what your program will get as well. you can tell, if the data is all right or not, don't you?
[08:57:38] <joelmoss> anyone familar with the Ruby BSON gem? I’m trying to convert BinData(3) to a string, but failing. can someone help please?
[09:07:31] <ranman> joelmoss: I'm trying to figure it out... but I don't know ruby very well so it might take me a bit
[09:17:19] <ayrus> Hi, Is there is any option to change the keys while fetching the data from MongoDB. Like in SQL (SELECT `user` AS `User1` FROM ~)
[09:22:42] <joelmoss> I think my problem is that the data is written by a Java app, but I need to read it from a Ruby app, so the byte order is different
[09:25:39] <ranman> http://stackoverflow.com/questions/8244110/get-bindata-uuid-from-mongo-as-string
[09:38:46] <joelmoss> may have to dig into https://github.com/mongodb/mongo-csharp-driver/blob/master/uuidhelpers.js
[11:58:14] <nofxx_> Crazy, strange issue, got a find() in my system was working flawless yeasterday, today its a devil's playground.... crazy pattern: 5 finds, 0.0042s each, then comes a 30seconds one! then 5 fast, 1 slow, 5 fast, 1 slow...
[12:00:33] <nofxx_> nEosAg_, now there's lot of stuff running, but earlier on the morning same issue w/o load. mongodb 2.6.3
[14:19:34] <adamcom> lgm: realise it has been a while since you asked but basically if you are wiping and starting from scratch you can just drop the config database and then restart everything - all shard config and other meta data live in the config database (on the config servers), so once you delete it (and restart to make sure the old data is not cached somewhere) then you are back to square one. The removeShard command (as you have found) is for altering the config of an
[14:30:03] <adamcom> Derick: likely, but I refuse to run more than one, so I must sacrifice quality for broad compatibility
[15:05:33] <PeepDurple> Good day. I have a question related to updating an list of arrays. I have something like this in my documents -> http://pastebin.com/mhpKzVxD .. can someone explain how I can remove the second array out of the list entirely? It seems like there is no trivial way out there for this
[15:08:24] <mipo> is there any manual or books about how to develop mongodb core? I wish to develop mongodb core
[15:12:55] <PeepDurple> It was just an example. Its a list containing n-amounts of addresses. I want to remove one address out of this list by using an index or in a similar way.
[15:12:56] <Derick> PeepDurple: you should be able to do: db.collection.update( { _id: YOUROBJECTID }, { $unset: { 'FOO.1' : true } } );
[15:13:37] <Derick> PeepDurple: you should be able to do: db.collection.update( { _id: YOUROBJECTID }, { $pull: { 'FOO' : {contentsobject }} } );
[15:52:03] <saml> hello, I have docs like {_id:1}, {_id:3}, .... where _id are natural numbers. not packed. there are jumps like 1, 2, 6, 50, 230 ... etc
[15:52:28] <saml> given an existing _id, can I have one query that gives me successor and predecessor ?
[15:54:06] <saml> db.docs.find({_id: {$lt:10}}).sort({_id:-1}).limit(1) db.docs.find({_id:{$gt:10}}).sort({_id:1}).limit(1)
[17:21:59] <und1sk0> { "ok" : 0, "errmsg" : "couldn't initiate : need all members up to initiate, not ok : mongodb2-us-east-1:27018"
[17:24:26] <und1sk0> also, has anyone had problems with keyFile auth for replication after upgrading from 2.4 -> 2.6?
[19:57:33] <freeone3000> I'm using mongo 2.6.4, and my members of a replica set are taking way too long to sync records.
[19:59:36] <deanclkclk_> and how do I provide the primary server IP address for the now secondary mongo?
[20:18:16] <deanclkclk_> I just stepDown a primary server and I want to make it a slave of another primary mongodb
[20:28:06] <cheeser> when a primary steps down, it'll be secondary for one of the other machines in the replica set. that will happen automatically.
[20:41:46] <freeone3000> My secondary is stuck in "still syncing, not yet to minValid optime 540e1259:1"
[20:44:41] <RealNitro> I aborted the mongodump command (ctrl-c), since then, my mongodb refuses to do any work...
[23:32:35] <joannac> zfjohnny: erm. you can either tail the mongod log with a grep to filter out other stuff
[23:32:58] <zfjohnny> In my mongod log file, there are no queries… just information about connections.
[23:40:05] <zfjohnny> is that somethign I can do in my mongo conf file? If so, what’s the commadn exactly? I’m a little confused about the syntax. Thank you for your help!
[23:40:58] <freeone3000> What is causing my replication to take forever? My infomessage on my seocndary has said "still syncing, not yet to minValid optime 540e1259:1"" for three hours.
[23:43:49] <freeone3000> rs.printSlaveReplicationInfo() says that I'm 0 secs behind the primary, so why am I in "RECOVERING"?
