It's hard to overstate the impact WiredTiger technology has had on MongoDB. When MongoDB announced its storage engine API in 2014, the WiredTiger team immediately saw the opportunity and raced to provide the best solution. The rest, as they say, is history.

Since the very inception of MongoDB, Eliot Horowitz, MongoDB's CTO and co-founder, has been a consistent and articulate owner of the MongoDB technical vision and the apparent creative force behind MongoDB's architecture and feature set. In appointing replacement CTO Mark Porter, MongoDB has chosen someone with a high degree of "geek cred" that will hopefully satisfy developers who want to hear from someone who can speak their language. However, he also brings experience from the enterprise database and cloud world that will undoubtedly be useful.

MongoDB has worked hard over the past few years to improve the security of its flagship MongoDB database server. It desperately needed to do this because MongoDB has been subjected to more high-profile attacks than any other database platform.

This year, an in-person MongoDB World conference in New York City was inconceivable. With NYC and the world still in various levels of COVID-19 lockdown, MongoDB World was held in the cloud as a virtual event—MongoDB.Live—in the first week of June. Holding the annual conference in the cloud is quite apt in many ways.

To predict how MongoDB may navigate COVID-19 and post COVID-19 environment would require an ability to predict how our industry as a whole will fare—which is a big ask. Nevertheless, let's give it a shot.

When I was a young man—a long, long time ago now—I worked as an Oracle DBA (Oracle version 6, if you must know). I remember my astonishment at finding out that information in the database was stored in plain text within the database files. That meant if I could gain read access just to those files, I could read all the information in the database. It didn't matter what security controls I, as the DBA implemented at the database level—an attacker who could gain read access to the files on disk could read everything.

Despite the failed promises of the data lake, the concept retains some resonance in larger enterprises, and so MongoDB has chosen to leverage the term for one of its latest offerings. MongoDB's Atlas Data Lake bears only superficial similarity to Hadoop-powered data lakes. Nevertheless, it's a useful feature that stands to see significant uptake.

MongoDB 4.2 may seem like a grab bag of features, but all of the features represent useful additions to your MongoDB toolkit. Some features—the Atlas Data Lake, for instance—need significant enhancements to cover all conceivable use cases. Nevertheless, MongoDB 4.2 will be a useful upgrade and I'd expect it to be widely deployed.

MongoDB gained popularity with developers very early on, but serious database engineers were often skeptical about MongoDB architecture and implementation. One area that came under some criticism was cluster consistency.

If you have been wondering whether the tipping point for database-as-a-service (DBaaS) has arrived, it's instructive to look at the success of MongoDB Atlas.

MongoDB's recent and well-publicized new license—the Server Side Public License (SSPL)—was explicitly designed to prevent cloud vendors such as Amazon from deploying a MongoDB cloud service without paying MongoDB license fees. In early January, Amazon announced DocumentDB, a MongoDB-compatible cloud database service.

For some time now, the majority of open source investment has come from venture capital and mega-corporations. There is good reason to think that this level of patronage will not persist indefinitely. Should VC-funded open source companies fail to return on investment, then VC investment will dry up. The high-profile companies bolstering open source do so primarily for selfish motives and can't necessarily be relied on to do so forever. So it's essential that companies that develop and market open source products be able to generate some return on their investment.

It's been a while since MongoDB has felt threatened by another document database vendor. Historically, the closest contender for document database dominance was Couchbase, the offspring of the original CouchDB database, which arguably ignited the document database segment.

The MongoDB 4.0 release introduced multi-document transactions to the popular open source NoSQL DB. The lack of a transactional capability has been a key limiting factor in MongoDB uptake, so it's not surprising that the company, it's users and the technology press have been enthusiastic about this latest release. However, it's worth remembering that the transactional capabilities of MongoDB have been commonplace for many decades.
Posted September 04, 2018
The introduction of transactions in MongoDB 4.0 represents possibly the most significant change in MongoDB's architecture since its original release. The lack of a transactional capability previously defined the capabilities of the database: Without transactions, MongoDB was blocked from consideration for a wide range of application scenarios. With the implementation of transactions, MongoDB can for the first time truly claim to be a general purpose DBMS.

It's understandable that those new to MongoDB - a so-called "schema free" database - might assume that they no longer need to be concerned with the art-science of data modeling. However, in reality data modeling is just as important in MongoDB as in other databases. Indeed, because of some of the modeling principles for MongoDB are less well understood, arguably, more attention needs to be given to the data modeling process.

MongoDB 3.6 was announced publically in November and should be in production by the time this article is posted. There are no shock features in this version, but it is an attractive release that should see rapid uptake.

MongoDB recently announced some interesting, though incremental, enhancements. These included improved "joins" in the aggregation framework, better document validation using JSON schema, and more reliable behavior in the event of network failures. These features attempt to close the gap between the functionality of MongoDB and traditional relational databases - joins, schemas, and commits. On top of these incremental updates, MongoDB announced a couple of features that intrude on functionality usually provided by application servers or desktop programs.

MongoDB faced its worst-ever public relations challenge earlier this year when a spate of ransomware attacks plagued tens of thousands of Mongo instances. It's important to realize that we are not talking about some sort of obscure vulnerability here - these MongoDB databases were configured with NO passwords at all, and were easily found listening on the default port (27017) on publicly-accessible servers.

Welcome to the inaugural MongoDB Matters column, which will appear six times a year in Database Trends and Applications. Over the past 8 years, we've seen a truly once-in-a-generation explosion of new database technologies which have challenged—if not overthrown—the dominance of the venerable relational database. Of all these upstart databases, MongoDB seemed to us to most deserve dedicated coverage because of its strong momentum and adoption.
