InitializeUnorderedBulkOp ( );. var bulk defines a variable called bulk. db is a default variable which refers to current database. employees is the collection for which we are going to create Bulk builder.

is the methods that returns Bulk builder which will be used for mongoDB bulk insert.Now after we got the builder, we can insert documents into builder one by one.

My confusion was coming from BasicDBObject constructor. I could see that it receives (String key, Object value), but I did not know Java Driver takes care of operators such as '$in' as Strings, in the position of a key.
