mysqlreport v3.0 has been released (v2.8 & v2.9 were skipped) which finally has InnoDB reports for MySQL servers v5.0.2 and up. The documentation has been updated accordingly. The new options that invoke the InnoDB reports are –innodb (or -id), –innodb-only (or -ido), and –dpr (for the extra Data, Pages, Rows report).

Since this is the first release with InnoDB reports, feedback on the InnoDB reports is appreciated. Eventually, I’ll update the mysqlreport guide to explain the InnoDB reports. For now, I think the InnoDB reports are self-evident to those who know a little about how the InnoDB …

I'm flying back from Alfresco's quarterly management meeting, and looking through some of the data shared by the team. We're just one company in a rising tide of open source companies, so I'm not sure how much to infer from our numbers about open source, generally, but I thought I'd share, anyway. Perhaps the data will be useful for you, too, as you plan your own open source business.

A few points:

1. Lead Generation. Alfresco's website (Downloads/product trials) drives 72% of our leads, and documentation drives another 21%. Cold calls from sales people, direct mail, email, Google Adwords, and other sources you might imagine...almost nothing. To be fair, we don't really do direct mail or email campaigns yet, so it's not surprising that these bring in few leads.

   But we found (as SugarCRM and MySQL found before us) that PR, which leads to visits to our website …

Welcome to the 22nd edition of Log Buffer, a weekly compendium of postings and news from database-related blogs across the Internet.

Starting things off with a bang is Peter Zaitsev and his MySQL Performance Blog where he records his observations on a  recent set of benchmarks for both MySQL and PostgreSQL. He offers some comments on the InnoDB concurrency scaling issue that some might not be aware of (as indicated in the comments).  Dropping in for Database Soup, Josh Berkus also takes a look at the same set of benchmarks in …

Daniel Nichter has released version 3.0 of mysqlreport, one of my favorite tools for quickly comprehending the overall state of a MySQL server. The new version prints out the most important information about InnoDB. It looks like this: $ perl mysqlreport --innodb-only MySQL 5.0.26-standard-l uptime 3 9:57:51 Fri Dec 8 17:29:07 2006 __ InnoDB Buffer Pool __________________________________________________ Usage 1.25G of 1.25G %Used: 100.00 Read ratio 0.002 Pages Free 1 %Total: 0.

Here are some common SQL problems, all of which have related solutions: how do I find the most recent log entry for each program? How do I find the most popular item from each category? How do I find the top score for each player? In general, these types of "select the extreme from each group" queries can be solved with the same techniques. I'll explain how to do that in this article, including the harder problem of selecting the top N entries, not just the top 1.

I had a lovely dinner the other night with Nick McGrath, the head of Microsoft's UK platform strategy. (I can say words like "lovely" because I'm in London this week. I'll therefore also throw in the words "bloke," "top of the morning, guv'nuh!", and "Arsenal.") For all the bile I spill over Microsoft (and there is very good reason for it), I continue to be impressed by the company, as reflected in its people. I've yet to meet anyone in Microsoft's Linux frontline (aka, the counterinsurgency :-) that I don't respect and genuinely like: Nick, Jason Matusow, Bill Hilf, Martin Taylor (before he left Microsoft), Steve Mutkoski, Gutierrez, etc. Great, capable people.

What I like most about Microsoft is the intelligence it brings to bear on its competition. While many enterprise software companies persist in cramming their heads …
