Oracle acquired Sun on April 20, 2009, which means that MySQL belongs to Oracle. More than 400 days have passed, what is the outcome of this merger? Please read this article.

Last year's acquisition of Sun, let Oracle smooth a potential opponent MySQL revenue bag, the industry uproar, a moment of controversy, singing losers have, optimistic also have, MySQL's development prospects are closely watched by all parties.

Now, Oracle has had some time to do with Sun's acquisitions. What happened to MySQL after the merger? This article will be from the post-merger version of MySQL update status, the status of the MySQL development team members, and after the merger of the competitor emerged, Oracle and the MySQL community disputes, and so on four aspects to comb. Restore the actual status of MySQL after being acquired.

MySQL5.5 release release frequency significantly increased

MySQL5.5 's release is undoubtedly one of the most important releases of MySQL since it was acquired. "This is actually a major change," said Morgan Tock, a MySQL expert, Morgan tocker. It will trigger a great change in how MySQL is used. In the past, users were often initially using the MyISAM storage engine and then learned to move to a more powerful innodb of data management; It is time to use a more advanced and more complex storage engine from the start. We'll see more people start learning about InnoDB, and people who know the MyISAM engine will be a lot less. The topic of discussion is no longer "why do I turn from MyISAM to InnoDB?" Instead, "I've heard there's a MyISAM engine, and under what circumstances should I try it?" This is a very sensible move for MySQL.

In addition, Oracle recently said that the latest version of MySQL Enterprise is coming to market, and to show that Oracle is continuing to invest in MySQL.

In a press release, Oracle said that MySQL Enterprise Monitor 2.2 (MySQL Business monitoring 2.2) was one of the key components of the release. MySQL Enterprise Monitor 2.2 Not only enhances the monitoring of query performance, but also improves security and saves time in integrating with MySQL support. This version enhances the ability to collect, search, and view query performance data, enabling developers to analyze and filter patterns that may interfere with critical system resources.

In general, in the power of the open source community and the competition of Oracle system, MySQL itself shows the trend of accelerating development, perhaps in the Oracle system MySQL becomes more complete, more stable, more commercialized, the branch version of the community more open, with stronger key performance, Perhaps these two parallel paths of development can create a more powerful new MySQL. Of course, it doesn't rule out a bad situation.

High-level upheaval MySQL development team members are basically stable

Before we talk about the status of MySQL development team members, let's take a look at MySQL executives who have been out of work in recent months.

February 08, 2010 the MySQL veteran has resigned from Ken Jacobs, who has 28 qualifications.

March 22, 2010 One of MySQL's founders (Marten Mickos) became CEO of Eucalyptus Cloud computing.

April 13, 2010 MySQL database development team, Karen Tagan Pader (Karen Tegan Padir) joined Enterprisedb.

If you count David Axmark, the co-founder of MySQL who left office in Sun, Aichmark, another founder, Michael Widenius, and head of the MySQL community relationship Cahit. Kaj Arno, the original high-rise of MySQL with Oracle can hardly be said to be left.

Compared to the huge changes in the high-level, you might be more concerned about "where are the MySQL developers?" Blaine Acker, former technical director of MySQL, said that, except for a small number of people leaving, the majority of the others were Oracle's employees, only a small fraction of them left.

Let's take a closer look at the developer of each module.

First of all, the storage engine InnoDB, which is a very large piece of code, it has survived for several years, and now still belongs to Oracle, no InnoDB there is no 24x7 stable running database.

and the optimizer (Optimizer) developers were almost gone, and they went to Montyab.

As for the copy (Replication) function, except for the first version of the creator, others are in Oracle. The first version of the writer now serves as a consultant for different companies, but he left the MySQL team around 2002. The execution/trigger system is a crystallization of collaboration between multiple developers. "Before the stored procedure" code is basically written at that time, the change of the part is very small, the relevant people are basically the oracle.

Take a look at the MySQL parser (Parser), most of the code comes from the merging of Minisql and Unireg, after which the MySQL developer does the monolithic stored procedure that later appears in 5.0, after which the function is through the segmentation technique (partitioning) To achieve.

Developers writing connectors (Connector) are still at Sun, so far no one has heard of leaving.

The writer of the stored procedure had left in 2005 and chose to go home for fishing, but its impact was negligible.

As a result, most of MySQL's developers are still in Oracle.

New and old rivals are attacking MySQL users and the market.

A while ago, Twitter announced that it would phase out existing MySQL systems and switch to Cassandra Management information. Cassandra is a distributed, open-source database funded by the Apache fund that distributes massive amounts of data to a large number of inexpensive servers, thus piecing together a single point of failure-free information management cluster. Before Twitter, Facebook and Digg have started using Cassandra, and Cisco WebEx has used Cassandra to collect user feedback.

Recently, San Francisco, the new company Clustrix publicly declared that their products are more powerful and excellent, can complete MySQL do bad things, can be extended to store billions of of data, can replace MySQL completely. Clustrix products can interoperate with the MySQL protocol, so that applications no longer need code porting, and its presence will undoubtedly hurt MySQL's paid business.

In addition, the recent rise of the No-sql movement has also brought new choices to the IT industry. In addition to Cassandra, the No-sql movement's representatives include Hadoop, Google's Big Table, Memcachedb, Voldemort, Couchdb, and MongoDB. In this context, not only the large Internet enterprises have begun to abandon the relational database including MySQL, even some enterprises in the internal application, taking into account multimedia, e-mail, space and geographic information increased, but also began to adopt a non-relational database scheme.

Today's MySQL has to face a lot of problems, it has a low adoption rate in large-scale applications, and faces a strong competitor for PostgreSQL. Mr. Bruce Momjian, one of the founders of PostgreSQL, told IT168 reporters that PostgreSQL was better than MySQL.

Oracle and MySQL Community

Oracle has made 10 commitments to the MySQL community before the merger. After the merger, Oracle executives are launching a "show love" offensive for open source people, but the former MySQL elite has rallied to win the "Hearts" of database administrators and developers through the MySQL database branch.

At the MySQL conference last month, Michael Vedneus Michael Widenius, the father of MySQL, and the famous MySQL architect Blaine Acker Brian Aker, respectively, spoke to promote their respective MySQL branch databases. They believe that any company is unlikely to be the only provider of MySQL development or support services.

They clearly expressed the view that developers and companies supporting MySQL should be diversified, and that the MySQL branch database owner is the developer interested in the code, not one of the benefit-driven businesses.

Ironically, MySQL is now owned by the database giant Oracle, and the database giant is listed as a "founding sponsor" at this MySQL conference. At the MySQL user conference, Oracle Chief Software architect Edward Skeven (Edward Screven) tried to gain the trust of MySQL users, claiming that their databases were very secure because Oracle provided a complete set of support services for users.

Skeven promises to embed MySQL into Oracle's software architecture and management products in the future. This may, however, contradict the principle of independence and openness that open-source people aspire to.

It is clear that Oracle's annual OpenWorld conference failed to impress the database administrator and the developer's "heart," after Skeven's speech ended, only the MySQL community relations manager Colin Charles (Colin Charles) polite applause.

24 hours later, MySQL's father and MySQL top architect threw the opposite view of Skeven: Oracle's drive for community development is a good thing, but a single architecture and a single supplier are not conducive to innovation. Independence is why they stay away from Oracle, and they are a winning weapon for attracting users and potential code contributors.

The practice of these MySQL celebrities is a test for Oracle, which will verify the extent to which Oracle and the MySQL community fit in and tolerate differing opinions, and Oracle's commitment to time and money for MySQL meetings allows critics and branch MySQL leaders to freely express their views.
