MySQL Performance Blog gets new server.

Try number two. We have moved to the new server yet again, now it is server hosted by ServerBeach as recommended by Kevin Burton and few other guys. Lets hope this will run stable and we’ll not need to move it back in emergency in less than a week as we had to last time. […]

New variable slave_max_allowed_packet for slave servers

One month ago I wrote about how a big read_buffer_size could break the replication. The bug is not solved but now there is an official workaround to ease this problem using a new configuration variable: slave_max_allowed_packet This new variable will be available in 5.1.64, 5.5.26, and 5.6.6 and can establish a different limit on the […]

DROP TABLE and stalls: Lazy Drop Table in Percona Server and the new fixes in MySQL

Suppose you have turned on innodb_file_per_table (which means that each table has its own tablespace), and you have to drop tables in a background every hour or every day. If its once every day then you can probably schedule the table dropping process to run during off-peak hours. But I have seen cases where the […]

Percona Server and XtraBackup Weekly News, April 25th

Time for our weekly review of the news! The big news this week is that Percona XtraBackup is ready to try out on Windows. Otherwise, there’s just more steady progress. One quick note, sort of a “to whom it may concern,” is that the proper trademarked names of our products include “Percona Server”, “Percona XtraDB”, […]

Percona Server and XtraBackup Weekly News, April 18th

Last week wasn’t so active in terms of new development, because many of us were at the MySQL conference, of course. However, we did push out the XtraBackup 1.6 release, and began work on backporting some features from MySQL 5.6 to 5.1 for a certain large customer. Several of the features we’ve added in 5.0 […]

Percona Server and XtraBackup Weekly News, April 11th

Last week was rather less newsworthy in Percona Server land, as we spent a lot of time preparing for the MySQL Conference and Collaborate, and Vadim was on vacation. One interesting tidbit: I wrote some scripts analyze our log files and found that we were massively under-counting the number of downloads for Percona Server, due […]

Percona Server and XtraBackup weekly news, April 4th

Here’s the weekly review of Percona Server and XtraBackup news. Before I begin, let me briefly address a common question. We are sometimes asked about our plans in light of developments in the market such as MySQL 5.5, MariaDB, Drizzle, etc. The short answer is that we’re very happy with Oracle’s GPL’ed MySQL releases as […]

Percona Server and XtraBackup weekly news, March 28th

It’s time for the weekly roundup of news for Percona Server and XtraBackup. To follow up on my note from last week, we’re still checking and validating the download stats. It appears that Percona Server has been downloaded well over 100,000 times, and Percona XtraBackup has been downloaded over 200,000 times. But when we changed […]

Percona Server and XtraBackup weekly news, March 19th

Here’s what is new in Percona Server and Percona XtraBackup since last week. We are working on compiling and checking download statistics for both pieces of software. The preliminary numbers are far higher than I thought they would be. Both Percona Server and XtraBackup are becoming amazingly popular. I am aware of deployments running into […]
