MongoDB Certified DBA

MongoDB University Offers Comprehensive Exams Worldwide

NEW YORK, NY- Nov 6, 2013 - I am very glad to announce that I have earned certification as a MongoDB Certified DBA, Associate Level. 

About a month ago, I was offered to try out MongoDB Certified DBA exam as part of a pilot project, invitations only. Before that, I successfully passed both M101 and M102P courses (well that was almost a year ago).  Invitations were sent to a selected group only, and only 150 first were given a chance to try that exam. It was thrilling to receive congratulating email in my inbox today, saying that I have successfully passed this quite difficult exam. Certificate number is 100-000-011 which indicates me being 11th in the world getting this (links to verify will be available little bit later).

According to The 451 Group's analysis of LinkedIn® member profiles, MongoDB is the most popular NoSQL database and now accounts for 49 percent of all mentions of NoSQL technologies. The formal certification will expand this reach and enhance the already thriving MongoDB online community.
I have been using MongoDB in production for about a year now. To keep things scalable, we have 3-node replica set (no sharding, yet) which has suffered no downtime since launch. Continuing being MongoDB NoSQL advocate in our company and mentoring, teaching and tutoring others will be my primary goal. We are already porting some of our products from MySQL Multi-AZ setup to MongoDB, and new apps will be built only on NoSQL, which allows us rapid growth and agile development.

Want to get certified? Here's what you need to know.


  • Philosophy & Features: performance, JSON, BSON, fault tolerance, disaster recovery, horizontal scaling, and the Mongo shell
  • Create, Read, Update, and Delete (CRUD) operations
  • Indexing: single key, compound, multi-key, mechanics, and performance
  • Aggregation: pipeline, operators, memory usage, sort, skip, and limit

Stubbing and Mocking Static Methods with PHPUnit

Image
PHPUnit has ability to stub and mock static methods. Consider the class Foo : <?php class Foo { public static function doSomething() { return static::helper(); } public static function helper() { return 'foo'; } } ?> To test the static helper() function with PHPUnit, you can write you test like that: <?php class FooTest extends PHPUnit_Framework_TestCase { public function testDoSomething() { $class = $this->getMockClass( 'Foo', /* name of class to mock */ array('helper') /* list of methods to mock */ ); $class::staticExpects($this->any()) ->method('helper') ->will($this->returnValue('bar')); $this->assertEquals( 'bar', $class::doSomething() ); } } ?> The new staticExpects() method works similar to the non-static expects...

MongoDB: Remove an Arbiter From a Replica Set

Image
Removing an arbiter from MongoDB Replica Set can be quite tricky, and official MongoDB documentation does not say it directly how to do it. I assume that you have auth enabled (just like I have), so lets start with connecting to your ReplicaSet "repl" master as an administrator: mongo mongo.domain.com/admin -u admin -p pass You will see the following prompt: repl:PRIMARY> Type in conf=rs.conf() repl:PRIMARY> conf = rs.conf() { "_id" : "repl", "version" : 8, "members" : [ { "_id" : 0, "host" : "mongo.server.com:27017", "priority" : 2 }, { "_id" : 1, "host" : "mongo1.server.com:27017" }, { "_id" : 2, "host" : "arbiter.server.com:27017", "arbiterOnly" : true }, { "_id" : 3, "host" : "mongo2.server.com:27017" } ] } Now lets adjus...

Enable HTTP/2 Support in AWS ELB

Image
This thread  was started more than a year ago, asking for when Amazon Web Services will add support for HTTP/2  into their ELB. In addition to that, people are also asking, how to configure ELB to support multiple SSL certificates. AWS support team has been reluctant on giving out any specific details on when both of these features will be available, citing: I've verified that the ELB team is aware of the interest in ELB supporting HTTP/2. Please keep an eye on What's New from Amazon Web Services: http://aws.amazon.com/new/ for any updates. What is HTTP/2? HTTP/2 is a replacement for how HTTP is expressed “on the wire.” It is not a ground-up rewrite of the protocol; HTTP methods, status codes and semantics are the same, and it should be possible to use the same APIs as HTTP/1.x (possibly with some small additions) to represent the protocol. HTTP/2 protocol is supported by major modern browsers including IE11, Edge 13, Firefox 47, Chrome 52, Safari 9.1, Opera 38, ...
