mongodb-query

I run a java program which is a thread executor program that inserts thousands of documents to a table in mongodb. I get the following error Exception in thread "pool-1-thread-301" com.mongodb.MongoWaitQueueFullException: Too many threads are already waiting for a connection. Max number of threads (maxWaitQueueSize) of 500 has been exceeded. at com.mongodb.PooledConnectionProvider.get(PooledConnectionProvider.java:70) at com.mongodb.DefaultServer.getConnection(DefaultServer.java:73) at com.mongodb.BaseCluster$WrappedServer.getConnection(BaseCluster.java:221) at com.mongodb.DBTCPConnector

Mongoid don't have timeout option. http://mongoid.org/en/mongoid/docs/installation.html I want Mongoid to kill long time queries. How can I set Mongoid query timeout? If I do nothing, Mongoid wait a long time like the below. mongo > db.currentOp() { "opid" : 34973, "active" : true, "secs_running" : 1317, // <- too long! "op" : "query", "ns" : "db_name.collection_name", "query" : { "$msg" : "query not recording (too large)" }, "client" : "123.456.789.123:46529", "desc" : "conn42", "threadId" : "0x7ff5fb95c700", "connectionId" : 42, "locks" : { "^db_name" : "R" }, "waitingForLock" : true,

In my model definition, I have: appFeatures: [{ name: String, param : [{ name : String, value : String }] }] I want to set default value to appFeatures, for example: name: 'feature', param: [{name:'param1',value:'1'},{name:'param2',value:'2'}] I tried to do it by appFeatures : { type : Array , "default" : ... } But its not working, any ideas? Thanks Mongoose allows you to "separate" schema definitions. Both for general "re-use" and clarity of code. So a better way to do this is: // general imports var mongoose = require('mongoose'), Schema = mongoose.Schema; // schema for params var

I was fortunate enough to get an awesome answer to another SO question Mongo / Mongoose - Aggregating by Date from @chridam which given a set of documents like: { "_id" : ObjectId("5907a5850b459d4fdcdf49ac"), "amount" : -33.3, "name" : "RINGGO", "method" : "VIS", "date" : ISODate("2017-04-26T23:00:00Z"), "importDate" : ISODate("2017-05-01T21:15:49.581Z"), "category" : "Not Set", "__v" : 0 } { "_id" : ObjectId("5907a5850b459d4fdcdf49ba"), "amount" : -61.3, "name" : "Amazon", "method" : "VIS", "date" : ISODate("2017-03-23T00:00:00Z"), "importDate" : ISODate("2017-05-01T21:15:49.592Z"), "category

We can use $push (to add an element into an array) in update to atomically update a single document containing the array However, I could not find a way to atomically add a new key to a map in a document. I could * read the document, * read the map in it, * update the map in my code and * update the document in my code. But that is not atomic. I am only dealing with a single document but that document has a map. Is there a way I can update (add a new key) map atomically? Dot notation with the $set operator is how you address individual elements. Take the following document: { "_id": 1, "map":

I have the following schema. { posts: [ { _id: '5ayuunbdsyuuuyut778' replies: [{ _id: "67hfudj7e9whduu888", text: "something" }] } ] } I want to update the text in particular reply. I am using mongoose. I have written the query as follows Post.findOneAndUpdate( {'posts.replies._id': _id}, {$set: {'posts.$[post].replies.$[reply].text': "something1"}}, { arrayFilters: [{'post._id': postId}, { 'reply._id': _id }]} ) This query is not updating the document. Am I missing something? Do I need to cast ids using ObjectId You need to use new: true to get the updated value and cast id to mongoose

I have following documents: doc1: { 'array': [ {'field': 'ABC', 'enabled': 'false'}, {'field': 'BCD', 'enabled': 'true'}, {'field': 'DEF', 'enabled': 'false'}, {'field': 'XYZ', 'enabled': 'true'}, ] } doc2: { 'array': [ {'field': 'ABC', 'enabled': 'true'}, {'field': 'BCD', 'enabled': 'true'}, {'field': 'DEF', 'enabled': 'false'}, {'field': 'XYZ', 'enabled': 'true'}, ] } I'm performing search by particular field. I want to get all documents that have this field enabled, and there are no other fields enabled before this (in the list). For ex.: search for field: BCD , enabled: true - should

I've been looking for this question one week and I can't understand why it still don't work...
