MySQL Table Sync efficiently finds and resolves data (not structural) differences between two MySQL tables, which may be on different servers. It offers two search algorithms to find the rows that differ, and several methods to bring the destination table into sync with the source.

MySQL Toolkit's Show Grants tool makes it easy to extract grants from a MySQL server in canonical form. You can use it to replicate grants between servers, diff grants, and avoid spurious changesets in version control systems.

I'm continuing to add new tools to the MySQL Toolkit. MySQL Deadlock Logger is for extracting and storing information about the latest recorded InnoDB deadlock. It's not only easy to view the information from the command line, it's dead simple to store it back into a MySQL table for analysis. I think most users will find it handy to create a cron job to record the deadlocks automatically for later analysis.

I somehow introduced a syntax error into MySQL Table Checksum in the 1.0.1 release and didn't notice till just now. I've replaced the file in the Sourceforge release, but it may take a few hours for it to propagate to all mirrors. My apologies.

It's finally ready -- the new stable version of the innotop MySQL and InnoDB monitor. Version 1.4.0 brings you new features and enhancements I think you'll really enjoy.

Now that I have innotop hosted on sourceforge, I'd like to use the tools they provide, especially the forums and mailing lists. I've set up an innotop-discuss mailing list, which I hope you'll find a better way to get support than posting in the comments on this blog. I think I will close comments on all innotop-related articles I post, because I can't keep track of feedback in so many places.

I got a lot of very nice feedback on the three tools I recently added to the MySQL Toolkit project on Sourceforge, and found and solved several issues with quoting and password prompting, index types, and so forth. Thank you all for your feedback, and welcome to Ruslan Zakirov, who plans to add some new tools!

I've updated MySQL Query Profiler, which I consider the most important tool I've written. It's now included as part of the MySQL Toolkit project on Sourceforge.

I've just released MySQL Duplicate Key Checker on SourceForge. This is a complete rewrite of a tool I initially released under a slightly different name. It is now much more powerful and friendlier to use, especially for scripting, and has many more options.

MySQL Table Checksum is a tool to efficiently verify the contents of any MySQL table in any storage engine. You can use it to compare tables across many servers at once. The output is friendly and easy to use, both by eyeball and in UNIX command-line scripts. The provided MySQL Checksum Filter helps you winnow output so you only see tables that have problems.
