A customer of ours had an interesting problem regarding a query
that was taking too long, around 55s. Looking at the query with
the query profiler we found that it was spending most of its time
in the "statistics" phase. Now the query was pretty complex, it
contained nearly 20 tables with INNER JOINs, LEFT JOINs and even
some subqueries. However the tables were small and fetching all
the data shouldn't have taken the 55 seconds the query was
taking. The problem was that the optimiser was spending too much
time evaluating and finding the optimal execution plan.
There are two options in MySQL with which you can control the
optimiser's behaviour a bit. The first one is
optimizer_prune_level. The pruner discards non-optimal execution
plans early without evaluating them fully. It is turned on by
default and is not recommended to turn off unless there's a
really good reason. For testing purposes we turned the pruner off
for this query, but …

After quite a bit of work, we have now finally released our High
Availability for MySQL training course. This course focuses on
the different ways of achieving high availability for MySQL
servers. When creating the course we had to study a wide range of
different options to see what we would include as a possible
solution to the course. The course will cover the usual suspects
such as standard MySQL replication (including the semi-synch
mode), MySQL Cluster, disk-clustering and DRBD which has long
been used together with MySQL. We also cover some more unorthodox
HA solutions for MySQL, such as Schoner Active Clustering,
Continuent Tungsten etc.

classes, please visit our training page

For Finnish or Northern European readers of this blog, I just wanted to advertise that there is a great MySQL training coming up in Helsinki on the 3rd week of August. The trainer will be Oli Sennhauser from Switzerland. Oli is a former collague of mine from MySQL AB and is now an independent MySQL consultant - one of the best in Europe! The curriculum is targeted at developers (more dev than ops) that are already familiar with using MySQL, and will help you get a deeper understanding of InnoDB internals, high availability, caching and other advanced topics.
You can check it out or register at the Citrus website.
