After some hesitation (just take a look at list of guys which were editors of previous editions, and you'll understand my shyness) I decided to give it a try. so, here it goes – 57th edition, written by depesz
First of all, we'll start with some posts about my favorite database – PostgreSQL.
Lewis Cunningham on his An Expert's Guide to Oracle Technology blog writes about new product for EnterpriseDB (commercial DB based on PostgreSQL) – GridSQL, which looks like Oracle's RAC. Check also his writeup on second blog: EnterpriseDB News.
What's interesting is that EnterpriseDB and their PR agency got lately quite controversial, which was mentioned by Joshua Drake on his blog (he also links to mailing list archives with discussions about the situation), and by Peter Eisentraut on his personal blog. this entry is very important as it goes into details about EnterpriseDB's “PostgreSQL distribution for Linux".
zillablog – blog by Robert Treat, has very interesting entry about conforming to standards, and using them as a excuse not to add new functionality.
And as a final note from our (PostgreSQL) area – Dave Page wrote new entry on his blog about setting up SSL access on Windows – apparently there were some issues with pre-built binaries of OpenSSL.
Now, let's enter the territory of “the other" opensource database – MySQL:
Biggest news of the week was change in policies and availability of MySQL products – community server and enterprise server. it all started with Kaj Arnö's post on his “MySQL AB VP Community Whereabouts in a Nutshell".
Of course Kaj Arnö had to respond, so there went another post on his blog.
Journal of Patrick Galbraith informs us about his new addition to mysqldump – options specifically designed to simplify dumping replicated databases.
Charlie Cahoon's MySQL – Summer of Code tells us how to use global variables in MySQL Proxy. To be honest I haven't heard about it (MySQL Proxy) before, but now, after reading his post I read more about it, and the software looks great. Something like pgpool (for those of you who know PostgreSQL), but with more functionality.
On the the possible functionalities of Mysql Proxy is using this (together with Charlie's code) to transform it into automatic regression tests generator. Details are shown on Giuseppe Maxia's data charmer – it looks really cool.
Johan Andersson and Jimmy Guerrero both tell us about web seminar (and white papers) about MySQL Cluster. Unfortunately if you're in America – it's too late, your webinar was on 8th, but you can still catch webinar directed at EMEA users on 15th.
While we're at learning – Jay Pipes presents materials from his workshop about tuning mysql queries – a must read for every MySQL DBA.
On his diary, Erik Wetterberg, wrote about generating XML content directly from MySQL. Check also comment to this post, as it contains link to valuable resource .
Sergey Zhuravlev on Xaprb wrote about new extension for MySQL replication – slave delay. Interesting idea with some obvious, and some not-so-obvious uses.
At the end of MySQL section, I couldn't help but write about two posts highlighting 2 interesting bugs in MySQL code.
First is Vadim Tkachenko on MySQL performance blog which writes about issues with query cache while dealing with column-based privileges.
The other post highlights what looks to me as quite serious bug. It's Parvesh Garg's post on Optim MySQL, and it's about InnoDB engine repeating (in some situations) auto_increment values.
Oracle is not the database I use, but 2 posts got my attention:
Mark Brunelli in Eye on Oracle: a searchoracle.com blog let us know that white papers for newest Oracle (11g) are available for download.
Second post made me sad that we don't have such a thing in PostgreSQL. It's on Coskan's Approach to Oracle by Coskan Gundogar and tells about permanent (guaranteed) restore points. Great feature.
At the end one more post – not technically database related, but it deals with the human side of databases and (DB) conferences: Mark Atwood's Journal entry about what to do when you're going to speak at a conference.
That would be all in this edition of Log Buffer. I hope you liked my choice of posts, and if not, don't worry, in a week there will be another Log Buffer, this time hosted by Jay Pipes
