I've been doing some work with NodeJS on OpenShift and am facing a problem when I'm trying to run a Mosca server in a Node instance. The error I'm getting is as follows: [Error: /var/lib/openshift/5547bd284382ec394a000088/app-root/runtime/repo/node_modules/mosca/node_modules/mongodb/node_modules/mongodb-core/node_modules/bson/node_modules/bson-ext/build/Release/bson.node: invalid ELF header] js-bson: Failed to load c++ bson extension, using pure JS version I have recently created a new Application (on OpenShift) from scratch with a NodeJS cartridge and have cloned the sample app git repository

How to Insert more than one document in a Single statement using InsertMany() MongoDB Method in C# My MongoDB Database and Connections IMongoClient _client; IMongoDatabase _database; _client = new MongoClient(); _database = _client.GetDatabase("test"); var collection = _database.GetCollection<BsonDocument>("EmpInfo"); I'm having a Collection - BsonArray var EmpInfoArray = new BsonArray { new BsonDocument { {"EmpID", "100"}, {"EmpName", "John"}, {"EmpMobile", new BsonArray { new BsonDocument { {"MobNumber", "55566610"}, {"IsPreferred", true}, {"IsLive", false} }, new BsonDocument { {"MobNumber"

I'm trying to do CRUD operations on documents in MongoDB and C# . I would like to have fixed structured domain entities in C# with long meaningful property names but since the name of each property will be saved in MongoDB for each document, that's not a good idea. That's because property names will be redundantly saved in database and affect the total storage and performance. The solution I can think of to overcome this problem, is to use different names for properties in C# than in MongoDB which means a mapping between them is needed. One elegant way of doing this is to incorporate C#'s

We are migrating some data from MySQL to Mongo and have been adding extra fields to some of our DB tables for the ObjectId value of the migrated data objects. At the moment we are storing them as varchar(24) latin1_general_ci which works fine. However, for efficient storage/indexing we probably should convert back to the 12-byte binary value. Unfortunately, MySQL only seems to have native integer support up to 8 bytes . Is there another option - binary perhaps? Update : I am migrating from MySQL but only certain tables at the moment. So I first make duplicates of the objects in Mongo of a
