MySQL Cluster 7.5 is GA, best cluster release ever

I have been fairly quiet on my blog for some time. We've been very busy
developing new features for MySQL Cluster 7.5 and ensuring that the
quality is improved even further.

We're now very pleased to release a new version of MySQL Cluster.

MySQL Cluster 7.5 contains a number of new things that makes MySQL
Cluster even better.
1) You can declare a table as a READ_BACKUP table. This means that
the updating transactions will receive the commit acknowledge
a little bit later to ensure that we can always use any of the
replicas for reading. We will use the nearest replica for
committed reads, for locking reads we will still use the primary
replica to avoid deadlocks.

For applications that are mostly read-focused one can make it easier
to set this variable by setting the ndb-read-backup config variable
to 1 in the MySQL Server …

Connection Management in Database Jones

How does an application configure its database connection?  I find this to be a pretty interesting question. As the application moves from a developer’s workstation to a test harness, then to staging, and on to production, the database connection properties can change each time. …

I recently had the pleasure of attending the first OpenStack Days East conference in NYC. This was the first OpenStack Days event that we’ve had on the East Coast of the US, but I hope that it’s the first of many!…

Working with more than 64 CPUs in Powershell

Wrote this several months ago but was too busy to publish :-/

As noted in one of the previous blog post, I will use following terminology:

  • "Processor" is a piece of hardware you connect to a socket on the motherboard.
  • "Physical Core" is a physical computing unit built into the "Processor".
  • "Virtual Core" is a virtual computing unit built on top of "Physical Core" (i.e. HT is ON).
  • "CPU" is a computing unit inside the "Processor", either physical or virtual.


After a series of blogs on Windows performance counters and after releasing sysb.ps1 testing/benchmarking framework version 0.9RC (dbt2-0.37.50.10) I set out to eliminate some unknowns from the testing. First to tackle …

My endeavour to build MySQL on Windows

I recently worked a lot on getting my local Windows box to compile Windows.
I got a lot of help from the below link that took me a few steps towards the
solution.
http://www.chriscalender.com/resolving-the-bison-exe-m4-invalid-argument-error-when-building-mysqlmariadbxtradb-on-windows/

I had to save away my bison installation, uninstall it and then also
go into a registry editor and remove the various links to the Start Menu referring to
some help for Bison that had spaces in the registry. Resolving this meant that I could
manually run bison on the files in the mysql tarball and get the desired result. But it
was still not enough, I still had the same error when running a full automatic compile.

So then I found the …
