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 performance you get). IBM has fixed that recently and have announced the LC series of servers which start at $6.600 (see more here: http://www-03.ibm.com/systems/power/hardware/linux-lc.html).

So, whar about MariaDB …

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.

Practically, we’ve not seen an update for 5.1/5.2/5.3 since 30 Jan 2013 at the time of this writing. And its clear MariaDB Server 5.5 will have an extended support policy, as it ships in Red Hat Enterprise Linux 7. 

At this time it’s worth …

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 tagline, but really, this is akin to nitpicking on Mark Zuckerberg donating 99% of his Facebook stock to his new limited liability corporation charity (key: don’t look a gift horse in the mouth).

Apple has chosen to put …

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 ...continue reading "Using JSON’s Arrays for MariaDB Dynamic Columns"

MariaDB CONNECT storage engine handles access to JSON files through standard SQL. It comes with a set of UDFs (user defined functions) to manipulate the JSON format. This JSON content can be stored in a normal text column. This approach can be used to implement dynamic columns. The dynamic column concept was first introduced with ...continue reading "Using JSON as Dynamic Columns with MariaDB"

The post MariaDB Talks at Percona Live Data Performance Conference 2016 appeared first on MariaDB.org.

I’ve made two session proposals for Percona Live conference:

• Window functions in MariaDB covers Window functions, a new feature in MariaDB 10.2. As far as I know, this the first attempt to have a talk about this feature.
• Exploring MariaDB Query Optimizer with ANALYZE for statements is about making use of ANALYZE (actually, ANALYZE FORMAT=JSON mostly) from …

So this year the Percona Live conference has a new name — it is the “Data Performance Conference” (presumably for a much broader appeal and the fact that Percona is now in the MongoDB world as well). And the next new thing to note? You have to go through a process of “community voting”, i.e. the speaker has to promote their talks before via their own channels to see how many votes they can get (we tried this before at the MySQL & Friends Devroom at FOSDEM; in this case, please remember you also need to create a new account and actually vote while logged in).

I hope you vote for Sergei, Monty and my proposals!

1. Using and Managing MariaDB – a tutorial, …

The call for participation for Percona Live Data Performance Conference 2016 is still open. Deadline for submission is November 29th.

There are two immediately noticeable novelties in this edition:

• The name change. Not "MySQL & Expo" but "Data Performance Conference." It makes the conference open to a broader set of topics.
• The community voting. Proposals can get evaluated by the community before the review committee takes decisions.

I think it's a good choice. Other conferences adopt the same method. The attendees choose what they want to see and hear. In this case, it's mixed method, where the community voting is used as an indication for the review committee, which, by my understanding, has the final say.

Vote for my proposals!

Below are my proposals. Clicking on the links below …

The MariaDB CONNECT storage engine offers access to JSON file and allows you to see a external JSON file as a MariaDB table. A nice feature of the CONNECT storage Engine is its capability to auto discover a table structure when the table correspond to external data. In our case the CONNECT storage engine will automatically [...]
