Working with various projects using MySQL I observe a lot of problems are coming from very simple fact - product is designed containing features which developers do not know how to implement effectively.

In many companies you would see "waterfall" like approach for web application development at least on business-development boundary. Business people would dream up some features for developers to implement which developers simply take and implement as good as they can - unfortunately often not good enough to match performance and scalability requirements for the application.

In the end such approach may have nasty surprises - application gets serve performance problems due to features which might be not critical after all and even Business people would rather make things running fast than having these features working exactly as required.

So what is my point ? Only plan for features which you know how to …

MySQL Table Maintainer is a new utility to help you run table maintenance commands (ANALYZE, CHECK, OPTIMIZE, REPAIR) on your MySQL tables. It's part of the MySQL toolkit.

I've just released updates to all the tools in the MySQL Toolkit. The biggest change I made to most packages is using DBD to read MySQL's option files, though some packages got more significant updates.

I have downloaded the source for the latest SolidDB engine for MySQL and modified it to compile on Mac OS X PPC operating system. There were no new changes in my modification process, so any differences are specific to the engine and will be bug fixes and new features.

Currently I am running the mysql-test set on the new engine and modifying some of the tests to formulate a test base for newer versions of the SolidDB engine as it is released.

I have made a precompiled binary available for version v0064.

Over the last weeks I wrote a mysql-proxy which changes the way you operate with the MySQL Server.

A proxy can operate as Man in the Middle and pass through to network packets to the MySQL Server, but it also change the packets when needed. This opens the several possibilities like a

• pseudo server done
• injection proxy done
• load-balancing proxy done
• connection pool
• XA Transaction Manager
• replication client
• replication filter
• replication off-loader

Some of them are already implemented, some are only ideas for the future.

• http://forge.mysql.com/wiki/MySQL_Proxy has the source and the binaries
• …

The MySQL proxy got some final touches to make it ready for the first release:

• a command-line interface
• some more mode descriptions for the different modes of operation

You can choose between three modes for now:

• pseudo server
• injection proxy

* replication client

For the future we plan:

• connection pooling

* replication filtering and off-loading

The options so far:

$ mysql-proxy --help
  --listen-port=<port>                  port the pseudo mysql-server should listen on in server-mode (default: 4040)
  --server-port=<port>                  port of the remote mysql-server in proxy- and reverse-mode (default: 3306)
  --server-ip=<ip>                      ip-address of the remote mysql-server in proxy- and reverse-mode (default: 127.0.0.1)
  --replication-user=<user>             user-account …

MySQL Table Maintainer is a new utility to help you run table maintenance commands (ANALYZE, CHECK, OPTIMIZE, REPAIR) on your MySQL tables. It’s part of the MySQL toolkit. Overview This tool is designed to help you run maintenance commands on your MySQL tables. There is a MySQL-provided tool (myisamchk) that fills some of the same purposes, but there are important advantages to doing it with SQL commands instead. Unlike using myisamchk, you don’t have to ensure this tool has exclusive access to the tables!

I’ve just released updates to all the tools in the MySQL Toolkit. The biggest change I made to most packages is using DBD to read MySQL’s option files, though some packages got more significant updates. Overview I discovered some features I didn’t know the Perl MySQL driver had – features to read MySQL’s option files, mostly, though there are some other nice features I use occasionally (but which are very relevant to innotop).

Through Kristian Köhntopp’s blog, I ran into a funny posting about “The real difference between MySQL and PostgreSQL” on Andreas Scherbaum’s mostly PostgreSQL related blog. I’ve taken the liberty below post a cropped version of the central picture of that blog entry:
