If you did not read my first blog post about Mark Callaghan’s (@markcallaghan) benchmarks as documented in his blog, Small Datum, you may want to skim through it now for a little context.

On March 11th, Mark, a former Google and now Facebook database guru, published an insertion rate benchmark comparing MySQL outfitted with the …

Developing with MySQL and NoSQL
Employee_Team +1 Vote Up -0Vote Down

MySQL adopts a very different approach to 'NoSQL' than other databases. With the memcached plugin, MySQL provides the speed and high availability benefits of a standard 'NoSQL' database solution, while mitigating many of the drawbacks to this approach.

A traditional memcached application bypasses the SQL layer entirely, and stores all its data in memory. This makes data access extremely fast, but there is a risk that the data will disappear in the event of a system problem. 

The MySQL memcached plugin for InnoDB also bypasses the SQL and optimization layers, resulting in excellent performance. It goes further, writing key-value data …

Reflections on return to MySQL Community and Ecosystem
+1 Vote Up -0Vote Down

After a four year hiatus, my participation in last week’s Percona Live MySQL Users conference marked my official return to the MySQL Community and Ecosystem. As with earlier renditions this year’s “UC” was very well attended with a healthy mix of familiar faces and new blood, all coming together to discuss, present and explore the boundaries of the most popular and widely used open source database on the planet.  There were many good, informative keynote and technical sessions, BoFs and the exhibit hall was packed most of the operating hours with those …

Reports exaggerated
Employee +1 Vote Up -0Vote Down

I've been letting the blog rest recently, and not so recently as well.  The problem is not a lack of subjects, but a lack of time to do them any justice.  However it is quite sad to see that my last entry was in September 2012, so it is time to post again.

Of late I have been pondering what I have to say about :

  • Distributed MVCC and write-scaling
  • Different approaches to eventual consistency with replicated RDBMS
  • Various MySQL Cluster related topics
  • Various general rambling and unstructured topics

However, these will take some time to percolate and calcify. …

Why I Love Open Source
+3 Vote Up -0Vote Down

Anders Karlsson wrote about Some myths on Open Source, the way I see it a few days ago.  Anders' article is mostly focused on exploding the idea that open source magically creates high quality code.  It is sad to say you do not have to look very far to see how true this is.

While I largely agree with Anders' points, there is far more that could be said on this subject, especially on the benefits of open source. I love working on open source software. Here are three reasons that are especially important to me.

Are SQL Databases Dead?
+1 Vote Up -0Vote Down

I like the image of this city of Mesa Verde. It’s fascinating to see how ancient cities were built, especially as an inhabitant of one of the worlds largest cities today, New York. I’m a long time relational database guy. I worked at scores of dot-coms in the 90′s as an old-guard Oracle DBA, and […]

The USA's healthcare.gov site and LAMP
+3 Vote Up -1Vote Down

The USA's health care exchange site, healthcare.gov, has had well-publicized initial woes.

The New York Times has said one of the problems was the government's choice of DBMS, namely MarkLogic. A MarkLogic employee has said that "If the exact same processes and analysis were applied to a LAMP stack or an Oracle Exa-stack, the results would have likely been the same."

I don't know why he picked Exastack for comparison, but I too have wondered whether …

MySQL 5.7 : Over 1M QPS with InnoDB Memcached Plugin
Employee_Team +5 Vote Up -0Vote Down

Or I could place in the title – “Yes, we done it!”

After reaching 500K QPS in Read-Only on SQL queries, it was natural to expect a much higher performance level from InnoDB Memcached Plugin which is by-passing all SQL related layers.. However the story is not simple, and yet far from finished

While for today we have already our first “preview” results showing that we’re able to reach over 1,000,000 Query/sec level with the latest MySQL 5.7 code:

Log Buffer #346, A Carnival of the Vanities for DBAs
+0 Vote Up -0Vote Down

Economist says that Physics suggest that storms will get worse as the planet warms. Typhoon Haiyan in Philippines, bush-fires in Australia, floods in China, and extreme unpredictable weather across the planet is a sober reminder. Good news is that technology and awareness is rising, and so is the data. Database technologies are playing their part to intelligently store that data and enabling the stakeholders to analyze and get meaningful results to predict and counter the extreme conditions. This Log Buffer Edition appreciates these efforts.
