This is the fifth GA release of MariaDB 10.0, and 15th overall release of MariaDB 10.0.

This is primarily a bug-fix release. (MariaDB 10.0 is the current stable series of MariaDB. It is an evolution of the MariaDB 5.5 with several entirely new features not found anywhere else and with backported and reimplemented features from MySQL 5.6.)

Here are the main items of note:

MySQL 5.7.5 Overview and Highlights
+2 Vote Up -0Vote Down

MySQL 5.7.5 was recently released (it is the latest MySQL 5.7, and is the “m15″ or “Milestone 15″ release), and is available for download here and here.

As for the fixes/changes, there are quite a few (the official release was split into 3 separate emails), which is expected in such an early milestone release.

The main highlights for me were (though the enhancements, and potentially impactful changes, are definitely not limited to this list):

Exorcising the CAP Demon
+0 Vote Up -0Vote Down

Computer science is like an enormous tool box you can rummage through whenever you have a problem to solve. Most of the tools are sturdy and practical, like algorithms for B-trees. Some are also elegant, like consistent hashing in Dynamo. Finally there are some tools that you never quite figure out even after years of reflection. That piece of steel you are looking at could be Excalibur. Or it could be a rusty knife.

The CAP theorem falls into the last category, at least for me.  It was a major topic in the blogosphere a few years ago and Google Trends shows …

+1 Vote Up -0Vote Down

For this release, there was 1 “InnoDB Notes” and 1 “Functionality Added or Changed” bug fix (and 0 “Security Fix”), so not much there, but of course they should be noted:

  1. InnoDB Note: The –skip-innodb option is now deprecated and its use results in a warning. It will be removed in a future MySQL release. This also applies to its synonyms (–innodb=OFF, –disable-innodb, and so forth).

Replication from Oracle to MariaDB the simple way - Part 4
+0 Vote Up -0Vote Down

Now it's time to get serious about replicating to MariaDB from Oracle, and we are real close now, right? What I needed was a means of keeping track of what happens in a transaction, such as a LOG table of some kind, and then an idea of applying this log to MariaDB when there is a COMMIT in Oracle. And thing is, these two don't have to be related. So I can have a table which I write to and also have a Materialized View that is refreshed on COMMIT on, and I need a log table or something. And when the Materialized View is refreshed, as there is a COMMIT, then the log can be applied. From a schematic point-of-view, it looks something like this: …

Replication from Oracle to MariaDB the simple way - Part 3
+0 Vote Up -0Vote Down

In this third installment in this series, I'll explain why the smart solution I described in the previous post actually wasn't that good, and then I go on to explain how to fix it, and why that fix wasn't such a smart thing after all. So, this was the design we ended with last time:
We have Oracle replicating to a Materialized View, this to ensure that we can run triggers when the is a commit, …

Replication from Oracle to MariaDB the simple way - Part 2
+0 Vote Up -0Vote Down

The theme for this series of posts is, and indicated in the previous post, "Try and try, again", and there will be more of this now when I start to make this work by playing with Oracle, with PL/SQL and with the restrictions of Oracle Express (which is the version I have available).

So, what we have right now is a way of "sending" SQL statements from Oracle to MariaDB, the question is when and how to send them from Oracle. The idea for this was then to use triggers on the Oracle tables to send the data to …

Replication from Oracle to MariaDB the simple way - Part 1
+0 Vote Up -0Vote Down

Yes, there is a simple way to do this. Although it might not be so simple unless you know how to do it, so let me show you how this can be done. It's actually pretty cool. But I'll do this over a number of blog posts, and this is just an introductory blog, covering some of the core concepts and components.

But getting this to work wasn't easy, I had to try several things before I got it right, and it's not really obvious how you make it work at first, so this is a story along the lines of "If at first you don't succeed mr Kidd" "Try and try again, mr Wint" from my favorite villains in the Bond movie "Diamonds are …

MySQL 5.5.40 Overview and Highlights
+2 Vote Up -0Vote Down

MySQL 5.5.40 was recently released (it is the latest MySQL 5.5, is GA), and is available for download here:

http://dev.mysql.com/downloads/mysql/5.5.html

This release, similar to the last 5.5 release, is mostly uneventful.

There were 0 “Functionality Added or Changed” bugs this time, and 18 bugs overall fixed.

Out of the 18 bugs, most seemed rather minor or obscure, but there are 3 I think are worth noting (all 3 are InnoDB-related, regressions, and serious if you encounter them, so best to be aware of them):

  • InnoDB: An …
