Insight for DBAs, MySQL
When executing an ALTER TABLE, InnoDB (and XtraDB) will create two InnoDB transactions: One transaction is created when the table being ALTERed is locked by the server. This will show up as something like “TABLE LOCK table schema.table_name trx id XXXX lock mode S” in SHOW ENGINE INNODB STATUS. Another is created when adding or […]

Due to a bug in upstream MySQL ( http://bugs.mysql.com/bug.php?id=65745 ), we’ve decided to delay the release of the next Percona Server release until it is resolved. We had originally expected to release Percona Server 5.5.25-27.0 today and instead I’m informing you that we are not. Quoting Hartmut, who reported the bug: An UPDATE that should only modify […]

Where does software go while it’s waiting for release? The answer is: our experimental repository! For anywhere from a few days to a week before we release them, we stage our software releases in the TESTING download area and in separate software repositories for Debian/Ubuntu and CentOS/RHEL. This is so that we can co-ordinate things such […]

Percona is glad to announce the second beta release towards Percona XtraBackup 2.0!

I spent last week at linux.conf.au in Ballarat, Victoria (that’s the Victoria in Australia, not wherever else there may be one) which is only a pleasant two hour drive from my home town of Melbourne (Australia, not Florida). I sent an email internally to our experts detailing bits of the conference that may interest them […]

Once upon a time, it would have been considered madness to even attempt to create 30,000 tables in InnoDB. That time is now a memory. We have customers with a lot more tables than a mere 30,000. There have historically been no tests for anything near this many tables in the MySQL test suite. So, […]

or… “the case of Stewart recognizing parameters to the read() system call in strace output”. Last week, a colleague asked a question: I have an instance of MySQL with 100 tables and the table_definition_cache set to 1000. My understanding of this is that MySQL won’t revert to opening the FRM files to read the table […]

As Mark pointed out, there isn’t a lot of detail in the release notes about what could potentially be a very serious problem that is fixed in MySQL 5.1.60. I’ll repeat here the full documentation from the release notes: “InnoDB Storage Engine: Data from BLOB columns could be lost if the server crashed at a precise […]
