Lock-free vs. wait-free concurrency
+2 Vote Up -0Vote Down

There are two types of non-blocking thread synchronization algorithms – lock-free, and wait-free. Their meaning is often confused. In lock-free systems, while any particular computation may be blocked for some period of time, all CPUs are able to continue performing other computations. To put it differently, while a given thread might be blocked by other threads in a lock-free system, all CPUs can continue doing other useful work without stalls. Lock-free algorithms increase the overall throughput of a system by occassionally increasing the latency of a particular transaction. Most high-end database systems are based on lock-free algorithms, to varying degrees.

By contrast, wait-free algorithms ensure that in addition to all CPUs continuing to do useful work, no computation can ever be

Dear MySQL Users,

We’re happy to announce the second Release Candidate (RC) of MySQL Workbench.
Version 5.2.22 includes fixes for 76 bugs.

In case you didn’t know – MySQL Workbench is a modular product and is fully pluggable and scriptable. If you want to write a plug-in for Workbench 5.2, then stay tuned as we will be updating the documentation in the next week with all the details and examples you need on how to write your own plug-ins.

Plug-ins are great for extending or adding to workbench or for automating repetitive tasks. You can do things like adding to menus, exporting your Workbench models custom tailored for your coding environment, adding your own forms, and more. Python is our preferred scripting language but for simple scripts the Lua language can be used as well.

The first plug-in we added is called MySQL Doc Library. It can be used to read the MySQL

Announcing a new beta 10 release of MySQL Workbench. Version 5.2.20 includes new fixes for 49 bugs (P1 – 1, P2 – 7 , P3 – 39, P4 – 2)

A few new tips you might try. Some have been in the last 2 betas – but in case you haven’t noticed:

  • Once connected in SQL Editor – type control-T or command-T to add a new editor Tab
  • In the SQL Editor run a select. Highlight a cell (one with an image blob preferably) and right click (or command click) and select “Open Value in Viewer” or another option.
  • In a results set — select multiple rows — right click and “copy row content”
  • Click on snippets. Click on the selector and look at DDL and DML lists.
  • Add your own snippets selection drop down option by creating an empty file in the snippets folder and re-opening Workbench.
  • For example on Windows

    We’ve raised $1.2m to help build RethinkDB
    +0 Vote Up -0Vote Down

    2010 will be an incredibly exciting year for database technology. The amount of stored information has long been increasing exponentially, presenting unprecedented challenges for modern technology companies. Dropping RAM prices and affordable multicore CPUs have drastically changed the hardware profile of a typical server machine from what it was only five years ago. The emergence of solid-state drives is about to revolutionize database systems, enabling new kinds of applications we can barely envision today.

    The database technology we have been using for over four decades is about to become obsolete. At RethinkDB, we’re redesigning databases from the ground up to meet modern data management demands, and to take advantage of the latest advances in hardware. We’re working to breathe new life into database technology, from the low level intricacies of

    RethinkDB is switching over to Lisp
    +4 Vote Up -0Vote Down

    April Fools! We aren’t switching to Lisp (as much as we love the language). We couldn’t resist having a bit of fun.

    Over the past few months we’ve had many architectural discussions about the future of database technology. It quickly became apparent to us that C++, the language we used to develop RethinkDB, is not sufficiently expressive to build the next-generation database product. We realized that in order to design the database system of the future, we need to use a programming language of the future as well.

    We did a quick survey of programming languages and eventually narrowed down our choices to Erlang, Haskell, and Common Lisp. Two years ago, Damien Katz of CouchDB laid out the reasons why Erlang is a poor choice for database products. Many of his

    Rebench: cutting through the myths of I/O performance
    +2 Vote Up -0Vote Down

    A very wise systems programmer once told me: “Don’t guess. Measure.” Since then, I’ve learned the hard way that guessing too much about performance is death by a thousand cuts. For RethinkDB, dozens of factors for I/O alone affect performance (not to mention memory, buses, caches, and CPU cores). In order to design the fastest database on Earth, we constantly test the following factors:

    • Performance of read and write operations.
    • Behavior for random and sequential workloads:
      • For random workloads, the behavior of uniform, normal, and power distributions (with different distribution parameters).

    We’re happy to announce the availability of the next Alpha release of MySQL Workbench 5.2. There have been further improvements to the querying part and we added the foundations for the administration part (which will be onboard in the next alpha).
    On startup, MySQL Workbench 5.2 now doesn’t automatically create a new design-document anymore – thats for decreasing resource-usage when you only launch Workbench for running a few queries against your database. Also the fix to make Workbench work on Snow Leopard has been included in 5.2 now as well.

    Please download the program, take it for a test-drive and tell us what you think. But keep in mind, that this is still an alpha version – so be advised to not use it for production data! Also please note, MySQL Workbench files saved with version 5.2 cannot be opened with previous versions of our

    MySQL Workbench on Snow Leopard
    Employee_Team +0 Vote Up -0Vote Down

    As all you Mac users (and probably many non-Macies) know Apple released Snow Leopard (Mac OS X 10.6) recently, even though this release was announced for September previously. Since a large part of the MySQL Workbench user base works on OS X it was clear that many of you will test Workbench on the new OS. However, so far we haven’t had the opportunity to do the same (too busy fixing bugs on released OSes) and hence we did not know about incompatibility problems there.

    In the meantime several users did tests and reported us a crash on startup of the application, which means you cannot use MySQL Workbench on Snow Leopard for the time being. We are currently preparing build, test and developer machines with it and will hand out a fixed WB release as soon as possible. So, please stay patient. It’s only a matter of days.

    +2 Vote Up -0Vote Down

    This is the first post on the brand spanking new MMM for MySQL Community Blog. Expect posts on new features for this great project. Expect user experiences.

    So, your question is of course: what is MMM for MySQL and why haven't I heard of this before?

    Well, MMM for MySQL is a project that strives to provide a HA Solution for MySQL, with automatic failover between multiple masters and slaves. If set up properly, you don't have to worry anymore over downtime for upgrading to a new version of MySQL, or a new version of your application (=> large alter tables, addition of indexes, etc.)

    The project has recently reached it's version 2, which is a complete rewrite from scratch. We are now slowly seeing this being put into production, with some success stories making us happy already.

    I won't make it too long here, but look forward to hear more from us!
