[Read more]We receive this question about the ibdata1 file in MySQL very often in Percona Support.
The panic starts when the monitoring server sends an alert about the storage of the MySQL server – saying that the disk is about to get filled.
After some research you realize that most of the disk space is used by the InnoDB’s shared tablespace ibdata1. You have innodb_file_per_table enabled, so the question is:
What is stored in ibdata1?
When you have innodb_file_per_table enabled, the tables are stored in their own tablespace but the shared tablespace is still used to store other InnoDB’s internal …
[Read more]Percona Toolkit’s pt-archiver is one of the best utilities to archive the records from large tables to another tables or files. One interesting thing is that pt-archiver is a read-write tool. It deletes data from the source by default, so after archiving you don’t need to delete it separately.
As it is done by default, you should take care before actually running it on then production server. You can test your archiving jobs with the – dry-run OR you can use the –no-delete option if you’re not sure about. The purpose of this script is mainly to archive old data from the table without impacting OLTP queries and insert the data into …

[Read more]Poor pt-heartbeat 2.1: it was perfectly fine through Percona Toolkit 2.1.7, but it’s had a rough life since. Its troubles are finally over as of Percona Toolkit 2.1.10. At a conference recently, a user joked to me that “Percona Toolkit is awesome, but you really broke pt-heartbeat.” It’s true, and if you haven’t heard or experienced the story, here it is for the record.
Since the dawn of time, pt-heartbeat had computed slave lag like:
t1=time (Perl) --> replicate --> t2=time (Perl); lag = t2 - t1
Surprisingly, that worked for many years despite what should have been an obvious problem: different time zones: t1 could be in PST …

It was once said that “real artists ship.” In looking over the history of Percona software releases, we are currently shipping more software than ever before.
First, let’s look at Percona Server. Let’s look at all major versions: 5.1, 5.5 and 5.6 as well as the total for each year. The estimate for 2013 comes from assuming the second half of 2013 is similar to the first half.
Percona Server releases per year
In 2011, when Percona Server 5.5 came along, we see a sharp reduction in Percona Server 5.1 releases (remember that there’s at least one Percona Server 5.1 release for each Oracle MySQL 5.1 release, and this reduction is likely a reflection of the reduction of releases from Oracle). In 2011, 2012 and 2013 we see a pretty steady number of Percona Server 5.1 releases. It seems that 5.1 is not going anywhere yet.
For Percona Server 5.5, we see an increase in 2012, which likely mirrors an …
