The recent release of the MariaDB client libraries has prompted questions about their purpose as well as provenance.  Colin Charles posted that some of these would be answered in the very near future.  I have a couple of specific questions about the MariaDB JDBC …

The MySQL Community: Beleaguered or Better than Ever?
+4 Vote Up -1Vote Down

The  MariaDB Foundation announcement spawned some interesting commentary about the state of open source databases.  One recent headline cited the "beleaguered MySQL community." Beleaguered is a delightful adjective.  The OED tells us that it means beset, invested, or besieged.  Much as I like the word, I do not think it is an accurate or useful description of the MySQL community. …

On Monday afternoon, Neal Armitage and I will be speaking at Percona Live in London. It will be a three hours tutorial about Tungsten replicator.

Using this cookbook, any user can simply install multiple topologies, from the simple master/slave to all-masters, fan-in, and star.

Attached are the slides for my MySQL Connect talk Evaluating MySQL High-availability alternatives, which I will present today at 14:30 at the MySQL Connect conference.

Data Fabrics and Other Tales: Percona Live and MySQL Connect
+0 Vote Up -0Vote Down

The fall conference season is starting.  I will be doing a number of talks including a keynote on "future proofing" MySQL through the use of data fabrics.  Data fabrics allow you to build durable, long-lasting systems that take advantage of MySQL's strengths today but also evolve to solve future problems using fast-changing cloud and big data technologies.  The talk brings together ideas that Ed Archibald (our CTO) and I have been working on for over two decades.  I'm looking forward to rolling them out …

Automated Database Failover Is Weird but not Evil
+9 Vote Up -0Vote Down

Github had a recent outage due to malfunctioning automatic MySQL failover.  Having worked on this problem for several years I felt sympathy but not much need to comment.  Then Baron Schwartz wrote a short post entitled "Is automated failover the root of all evil?"  OK, that seems worth a comment:  it's not.  Great title, though.

Selecting automated database failover involves a trade-off between keeping your …
