MariaDB JSON text indexing
+2 Vote Up -0Vote Down

It is not new that we can store a JSON content in a normal table text field. This has always been the case in the past. But two key features were missing : filtering based on JSON content attributes and indexing of the JSON content. With MariaDB 10.1 CONNECT storage Engine we offer support for [...]

Web Security: SHA1 SSL Deprecated
+1 Vote Up -0Vote Down

You may not be aware that the mechanism used to fingerprint the SSL certificates that  keep your access to websites encrypted and secure is changing. The old method, known as SHA1 is being deprecated – meaning it will no longer be supported. As per January 2016 various vendors will no longer support creating certificates with SHA1, and browsers show warnings when they encounter an old SHA1 certificate. Per January 2017 browsers will reject old certificates.

The new signing method, known as SHA2, has been available for some time. Users have had a choice of signing methods up until now, but there are still many sites using old certificates …

Proposals Percona Live 2016
+0 Vote Up -0Vote Down


Ahoi, I made three proposals for Percona Live. (Even I know being a lonely (sniff) freelancer with no backup). At least I'm for sure an early adopter about the three topics I submitted and know for sure what I'm talking about *g*   

Even being Puppet certified. Ansible is my love. Never been that fast in doing automation \o/

SQL Games
+0 Vote Up -0Vote Down

I have just created a GitHub repository called sql_games. It contains games implemented as stored procedures, that can run on MariaDB or (with some changes) on Percona Server or Oracle MySQL.

You play the games via the command-line client. You call a procedure to make your move, then a text or an ASCII image appears.

Of course the same call should produce a different effect, depending on the game’s current state. To remember the state I use both user variables and temporary tables.

Why did I do that? Mainly because it was funny. I can’t explain why. And I can’t tell …

The State of SSL in MariaDB
+0 Vote Up -0Vote Down

Usually when one says “SSL” or “TLS” it means not a specific protocol but a family of protocols. Wikipedia article has the details, but in short — SSL 2.0 and SSL 3.0 are deprecated and should not be used anymore (the well-known POODLE vulnerability exploits the flaw in SSL 3.0). TLS 1.0 is sixteen years […]

The post The State of SSL in MariaDB appeared first on MariaDB.org.

POWER8 Accelerated CRC32 merged in MariaDB 10.1
+1 Vote Up -0Vote Down

Earlier on in benchmarking MySQL and MariaDB on POWER8, we noticed that on write workloads (or read workloads involving a lot of IO) we were spending a bunch of time computing InnoDB page checksums. This is a relatively well known MySQL problem and has existed for many years and Percona even added innodb_fast_checksum to Percona Server to help alleviate the problem.

In MySQL 5.6, we got the ability to use CRC32 checksums, which are great in that they’re a …

Getting started with MariaDB on IBM POWER 8
+0 Vote Up -0Vote Down

IBM POWER 8 is latest generation of the IBM POWER series, and it's a hot one. Above all, for you reading this, POWER 8 is the most Linux friendly so far and IBM really wants you to try this out. Seveal Linux distributions are supporting POWER 8 now, and MariaDB is of course the database of choise. Some cools things with the POWER 8 architecture are the support for CAPI (google for more details) and the fact that POWER 8 machines, due to a vastly superior memory architecture, can grow in memory size, which in general is good news but if you want your own POWER 8, this makes then a bit expensive (although maybe not when you consider the …

MariaDB Server GA’s supported for 5 years
+1 Vote Up -0Vote Down

There was some discussion a while back to maybe make MariaDB Server follow the Ubuntu release model, i.e. having a Long Term Release (LTS) and then having a few regular fast releases with a shorter support cycle.

However its good to note that the decision now going forward is to support each and every GA release for a period of five (5) years. However, regular releases will only happen for the latest three (3) GA releases, so at this moment, you are getting updates for MariaDB Server 5.5/10.0/10.1.

Learnings from Swift becoming opensource

Swift is now opensource, and it’s interesting to see Craig Federighi talk about it. This is Apple doing right, considering FaceTime is long overdue to being an open standard. People are nitpicking on Apple’s Open Source …

Using JSON’s Arrays for MariaDB Dynamic Columns
+0 Vote Up -0Vote Down

The JSON format includes the concept of array. A JSON object cant contain an attribute of array type. We have seen that we can use the MariaDB CONNECT Storage Engine provided UDFs (user defined functions) to implement dynamic columns.

Let us create a table with a text column containing a a JSON string and let [...]
