As I wrote a few days ago, I'm writing the replication chapter for the second edition of High Performance MySQL. I'm writing about replication filtering rules right now, and I thought it would be good to get input on this. If you have favorite replication filtering tricks you'd like to share, or tasks that always frustrate and/or confuse you, please post them in the comments. I'm making a section that shows how to accomplish common filtering and rewriting needs, such as preventing GRANT statements from replicating to the slaves.

Thanks very much! I hope the community involvement will make this book more useful for everyone.

Hello everyone, I think this will be a great log buffer. Dave has been sick these past two days and as a result, we do not have a comprehensive log buffer ready the way we or a volunteer usually do. This was bound to happen to log buffer at some point and today it has happened. So I [...]

Continuing in the tradition, which I hope has been as helpful to you as it has been to me, I'm opening the floor for suggestions on chapter 9 of the upcoming High Performance MySQL, Second Edition. Unlike the other chapters for which I've listed outlines, this one isn't substantially written yet. It's in detailed outline form at this point (a tactic that has worked very well for us so far -- I'll write about that someday).

I'm trying to get feedback much earlier in this chapter's lifecycle, for several reasons. Two of the most important are that this is one of the first chapters I've had a chance to really take from scratch, and the chapters I haven't written from scratch have been harder to organize, as you've probably seen from the last few outlines I posted. There's a lot of value in working top-down on this deep encyclopedia-style material.

Read on for the outline and more thoughts I just can't keep to myself.

The new release of MySQL Toolkit (version 1051) updates MySQL Parallel Dump in minor ways, but more importantly, it adds MySQL Parallel Restore. Read on for details.

I was just searching for something and found this MySQL bug report:

Other JDBC drivers I have used make toast for breakfast... MySQL Connector/J doesn't make toast, it can only pour a bowl of froot loops...

...Thank you for taking the time to write to us, but this is not a bug... I believe you should look into a device called a \"toaster\" to make your toast.

I've been trying to circle back and clean up things I left for later in several chapters of High Performance MySQL, second edition. This includes a lot of material in chapter 4, Schema Optimization and Indexing. At some point I'll write more about the process of writing this book, and what we've done well and what we've learned to do better, but for right now I wanted to complete the picture of what material we have on schema, index, and query optimization. The last two chapters I've written about (Query Performance Optimization and Advanced MySQL Features) have generated lots of feed back along the lines …

I am considering taking some time off work to concentrate deeply on MySQL Table Sync, which has been getting usage in very large companies whose names we all know. There are a lot of bugs and feature requests outstanding for it. It is overly complex, needs a lot of work, and I can't do it in one-hour or even three-hour chunks. I need to focus on it. I'm considering asking for a bounty of $2500 USD for this. Please let me know what you think of this; it seems to be a successful way to sponsor development on some other projects, like Vim.

For the amount of time I think this will take, $2500 is far below my per-hour consulting rate; I considered setting the bounty higher, but I think this will be a fair amount.

I would not begin this project before December at the earliest, so there's some time to raise funds and time for me to continue working on High Performance …

This release of MySQL Toolkit updates MySQL Parallel Dump. Together you and I found a few bugs in it (table locking, argument quoting, exit status code). The restore utility is in progress.

Your comments on the Advanced MySQL Features chapter were great. A lot of the questions I got (in the comments and via email) about chapter 6 are really addressed in chapter 5, "Query Performance Optimization," so I'm posting its outline too. I have the same questions: are there things you'd like to see us cover? Do you have any favorite techniques you'd like to see us include? Any other comments or questions?

Work continues apace on High Performance MySQL, Second Edition (the link leads to the chapter outline). I'm working now on Chapter 6, Advanced SQL Functionality, and thought I'd solicit input on it. Are there things you'd like to see us cover? Do you have any favorite techniques you'd like to see us include? Feel free to leave feedback in the comments. The chapter is already significantly done, with 26 pages written, but the ink's not on paper yet, so there's still time to correct omissions!
