For most queries, theįirst batch returned will be 101 documents The cursor will fetch results in batches from the database, so if you run a query that matches a lot of documents, you don’t have to worry that every document is loaded into memory immediately. In this case, you can create a query document that has the criteria you want:ĭBCursor results = collection.find(new BasicDBObject("name", "The name I want to find")) Īnd you can, naturally, iterate over them: You could be looking for all the people with a particular name, for example. In the real world, you won’t always know the ID of the document you want. Therefore you can useįind all documents matching some criteria In the above example, because you’ve queried by ID (and you knew that ID existed), you can be sure that the cursor has a single document that matches the query. …and you get the values out of the document (represented as a To recap, you can easily get a document back from the database using the unique ID:ĭBCursor cursor = collection.find(new BasicDBObject("_id", "theId")) That looks a similar shape to the one you want.įor the following examples I’m going to assume a document which looks something like this: As I mentioned, you can query by example, building up a
But MongoDB supports more than simply getting a single document by ID or getting all the documents in aĬollection. In the last article we covered some basics on usingĭata from the database. Putting stuff in the database is all well and good, but you’ll probably want to query the database to get data from it. But if you want a reminder, or simply want to skip to playing with the code, you can take a look at

As in the previous article, if you want to follow along and code as we go, you can use these tips to get the tests in theĪnd how to create them from Java and insert them into MongoDB, so I’m not going to repeat that here. In this post, I’ll give an introduction to CRUD (Create, Read, Update, Delete) operations using the Java driver. , we covered the basics of installing and connecting to MongoDB via a Java application.

Many things changed in the Java driver since then. This blog post from 2014 is now very deprecated. Getting Started with MongoDB and Java: Part II In addition to EA, Kixeye and a variety of other gaming companies use MongoDB to improve the gaming experience. Park, who played for years for Manchester United and tormented Arsenal defenses, “congratulate Spearhead on the great performance of FIFA Online 3,” performance enabled by its underlying MongoDB data infrastructure. Not content to win accolades on the field, EA FIFA Online 3 has also garnered honors from the industry, most recently winning a MongoDB Innovation Award, due to its creative use of MongoDB.Įven better, EA's Spearhead, recipient of the $2,500 award for its work, donated it to the Park Ji-sung JS Foundation. As EA FIFA Online 3 continues to grow in popularity, EA expects MongoDB's autosharding and other features to make it simple to scale. EA already runs 250 MongoDB servers, spread across 80 shards. (More on him later.)īecause EA FIFA Online 3, developed by Spearhead, one of EA’s leading development studios, needs to scale to millions of players, Spearhead built the game to run on MongoDB, the industry's most scalable database.
The massively multiplayer online soccer game is the most popular sports game in Korea, allowing players to choose to play and customize a team from any of over 30 leagues and 15,000 real world players. Throughout Asia one of the most popular ways to bend it like Beckham is with EA’s FIFA Online 3. Not everyone chooses to play FIFA on their XBox or Playstation, however.
