In November, I wrote about the command SHOW ENGINE INNODB MUTEX and
sought feedback as to how it continues to be used post
introduction of performance_schema.
The outcome from this feedback is that the MySQL team has decided to remove this command from MySQL 5.7.
These decisions are not light ones for the team to make. I wanted to thank everyone for their feedback, and also share why this decision was an important one for the future of MySQL:
SHOW ENGINE INNODB
MUTEX was always enabled, with no switch to disable it. We
believe that for some workloads being able to disable the
collection is useful, and in the case of
performance_schema this is possible.
performance_schema overlaps with this …Wed, 2014-03-05 09:35robertsilen

MySQL Fabric is a framework for MySQL Replication high availability, automatic failover and sharding. Technically, a MySQL Fabric daemon monitors a set of MySQL servers and takes appropriate actions upon failure. Clients use Fabric aware drivers to learn about failed servers and shards to distribute queries accordingly. Simple to understand, simple to sell, simple to raise false expectations and simple to fail [, dear Sales]. With the usual blog posts telling only the story of the first three sentences, major parts of the story are covered in silence.
Development preview = announcement of a vision != ready
You first challenge will be to find the documentation for the MySQL Fabric development preview. From the documentation overview page it takes three clicks down to the server side documentation for Fabric:
Percona is glad to announce the release of Percona Toolkit 2.1.11 on March 4th, 2013 (Downloads are available here).
Bugs Fixed:
Fixed bug 1279502: –version-check behaves like spyware
The configuration for what information Percona Toolkit should retrieve is not hard-coded in the scripts. Instead, it is downloaded from v.percona.com. One of the possible parameters was the name of a binary file to execute with “–version.” This was fixed by removing the ability to execute arbitrary binary files with the version parameter.

[Read more]Since 2011 e-commerce has grown from $856,000,000.00 to closing out 2013 at more than $1,248,000,000,000.00 in global revenues, a nearly 41% growth rate over a two year span. The forecast for 2014 is targeted at $1,500,000,000,000.00, another 20% increase is gross revenues (see chart below). With trillions of dollars in play year on year now, and astounding revenue growth rates still ahead, it is critical that any e-commerce site be diligently monitoring not just their website uptime, but more importantly their Web applications. Obviously it is critical that your customers be able to get to your website, but if it doesn’t build fast and complete client requests and transactions even faster then you will be losing clients and revenue at an alarming rate. The latest figures show that if your site doesn’t do a full page load in 3 seconds or less, …
[Read more]Unless you’ve been living under a rock, you’ve probably heard about driverless cars. Google and the large car makers have been creating cars that doen’t need a human driver. This is tremendous news. Over 30,000 people die in car crashes every year in the US. While not all of those could be prevented by removing the meatbag driver, a lot of them could. Driverless cars are the right way forward and I can’t wait until they come. Every time I see a car wreck or hear about a drunk driver, I wish we had this tech right now.
That said, our teens shouldn’t stop learning to drive defensively, our cops …
