I now enabled SQL-interface to table-reorg.

The syntax (which is the same for other partition mgm) is
ALTER ONLINE TABLE T ADD PARTITION PARTITIONS N;

Also switched so that hashmap partitioning is used for all tables created using SQL.
And mysql-test-run works (including a new ndb_add_partition-test)
(except for some range/list partition testcases)

it's still kind of fragile. Error handling is sparse...

there are 3 known things which are easy to fix
- ndbapi transaction hinting/pruning does not work after/during a reorg
- unique indexes will not work after/during a reorg
- only 1 reorg per table is possible (SUMA caches distribution information incorrectly)

and one quite hard
- cluster crash *during* table-reorg

current plan is
1) fix 3 easy known problems
2) fix error handling
3) write …

I guess I am bit late with these news... but.. IT IS GREAT NEWS!

Short summary (read more on Ramon's blog)

• Cluster was pulled out of 5.1.24
  
• Don't use 5.0 any longer
  
• MySQL Cluster 6.2 is what everyone should use (unless CGE 6.3 features are needed). It is a great piece of software, thoroughly tested by telcos and put in production around the world!
  

Why pull Cluster out of 5.1.24? As everyone knows 5.1.24 is delayed and at the same time CGE 6.2 has lived its own life and matured in production and in test labs.

Although the mysql server parts are based on 5.1.23 the …

During 2008 we are planning to run a series of interviews with interesting persons somehow related to the telecom field. In this first installment, we will have a chat with Juha Heinänen from Finland.

MySQL: Juha, you are a former professor of Computer Science and Communication technology, CTO (or similar positions) in at least Sonera, Telia and Song, former ATM specialist, responsible for bringing Internet to Finland and registering the .fi top-level domain, a consultant for many early network equipment startups some of which succeeded to be still with us today, and author of several RFC's. Nowadays you are a core contributor to the OpenSER SIP proxy, and you sell a VoIP platform called OpenSIPg based on that to Nordic operators. In addition you seem to live a life that would likely be a dream of many hackers, spending time in different parts of the world hacking on your favorite Open Source project. Even to this date, I …

Jonathon and I will be there, and I am speaking in the business track on Tuesday. It won't be about training or the other stuff that Open Query is doing, but instead provide a high-level (business) overview of MySQL's unique architecture. As we know, MySQL is particularly capable at doing a lot of things, but for optimal results the underlying architecture needs to be right, too.

Of course it is an excellent opportunity for us to meet some more potential customers too, as we now have a lot more training modules for developers, DBAs and High Availability. Our public course schedule for the coming months covers Brisbane, Sydney, Canberra, Melbourne, Adelaide and Auckland, and meanwhile …

Bruce Momjian says

…the volume of patches [to PostgreSQL] has risen dramatically during the past few years.

This is total hearsay — I don’t have hard numbers, haven’t verified it myself, etc etc. But consider the source!

What can be responsible for this increase in patches to PostgreSQL?

MySQL’s version numbering is getting harder and harder to understand. In fact, it’s getting surreal. Let me state up front that there’s probably a lot I don’t know here. But if I don’t know, how on earth can the general public figure it out? Before we begin, let’s define terms: GA is completely done, ready for use. RC is a release candidate: don’t change anything, just fix bugs because we’re charging towards a release here.

A couple of months ago, I wrote about the hierarchy of enterprise software needs, and today I would like to share with you how I think those needs have changed.

A long, long time (say ten years) ago, a company might decide that it needs to manage its sales effort more effectively. It might decide that a CRM system is what it needed, then buy servers, license a package, and then train, or at least try to train, its salespeople to use the system. They are told that they need to enter all their account and contact information into the system, log all their calls and meetings with clients, and fill out forms to record the sales opportunities. They will also have to make periodic forecasts with the system.

Needless to say, some sales people might resist, but it's up to management to make sure that they …
