Introduction:

To run MariaDB from Eclipse we will actually create and install the tar.gz package resulting from compilation(See Part 2) in a separate directory, this will allow us to have MariaDB cleanly installed on a separate location and so it will be also easily possible to run it independently from Eclipse.

In these Blog posts series we assume:

I’m pleased to say that Continuent will be at the Hadoop Summit in San Jose next week (3-5 June). Sadly I will not be attending as I’m taking an exam next week, but my colleagues Robert Hodges, Eero Teerikorpi and Petri Versunen will be there to answer any questions you have about Continuent products, and, of course, Hadoop replication support built into Tungsten Replicator 3.0.

If you are at the conference, please go along and say hi to the team. And, as always, if there are any questions please let them or me know.

This is the third post in our MySQL Fabric series. If you missed the previous two, we started with an overall introduction, and then a discussion of MySQL Fabric’s high-availability (HA) features. MySQL Fabric was RC when we started this series, but it went GA recently. You can read the press release here, and see this blog post from Oracle’s Mats Kindahl for more details. In our previous post, we showed a simple HA setup managed with MySQL Fabric, including some basic failure scenarios. …

Getting data into Hadoop is not difficult, but it is complex if you want to load 'live' or semi-live data into your Hadoop cluster from your Oracle and MySQL databases. There are plenty of solutions available, from manually dumping and loading to the good and bad sides of using a tool like Sqoop. Neither are easy and both prone to the problems of lag between the moment you perform the dump and

Running MySQL in the cloud offers many benefits, including extremely fast provisioning and deployment, managed security, and (mostly) easy operations. But nothing comes for free, and as with all things on this wonderful planet, those benefits come with certain limitations. Until recently, one of the significant drawbacks of MySQL on Amazon RDS was limitation of […]

MySQL has status variables “questions” and “queries” which are rather close but also a bit different, making it confusing for many people. The manual describing it might not be very easy to understand:

Queries
The number of statements executed by the server. This variable includes statements executed within stored programs, unlike the Questions variable. It does not count COM_PING or COM_STATISTICS commands.
 Questions
The number of statements executed by the server. This includes only statements sent to the server by clients and not statements executed within stored programs, unlike the Queries variable. This variable does not count COM_PING, COM_STATISTICS, COM_STMT_PREPARE, COM_STMT_CLOSE, or COM_STMT_RESET commands.

In a nutshell if you’re not using prepared statements the big difference between those is what …

First, I would like to invite you to my webinar, “Monitoring All (Yes, All!) MySQL Metrics with Percona Cloud Tools,” on Wednesday, June 25 at 10 a.m. Pacific Daylight Time, where I will talk on the
new features in Percona Cloud Tools, including monitoring capabilities.

In this post I’d like to show the cool and interesting things we’ve implemented in Percona Cloud Tools, including the recently released agent that Daniel also talks about here in this post.

Basically our agent allows users to collect ALL MySQL metrics plus important …

There is one new feature in MySQL 5.6 that didn’t get the attention it deserved (at least from me ) : “DATA DIRECTORY” for InnoDB tables.

This is implemented since MySQL 5.6.6 and can be used only at the creation of the table. It’s not possible to change the DATA DIRECTORY with an ALTER for a normal table (but it’s in some case with partitioned ones as you will see below). If you do so, the option will be just ignored:

mysql> CREATE TABLE `sales_figures` (
    ->   `region_id` int(11) DEFAULT NULL,
    ->   `sales_date` date DEFAULT NULL,
    ->   `amount` int(11) DEFAULT NULL
    -> ) ENGINE=InnoDB DEFAULT CHARSET=latin1
    -> DATA DIRECTORY = '/tb1/';
Query OK, 0 rows affected (0.11 sec)
mysql> alter table sales_figures engine=innodb data directory='/tb2/';
Query OK, 0 rows affected, 1 warning (0.21 sec)
Records: 0  Duplicates: 0  Warnings: 1
mysql> show warnings; …
