v2.0.3 released 2012-02-03
|
|
==========================
|
|
|
|
Percona Toolkit 2.0.3 has been released. The development team was very
|
|
busy last month making this release significant: two completely
|
|
redesigned and improved tools, pt-diskstats and pt-stalk, and 20 bug fixes.
|
|
|
|
Both pt-diskstats and pt-stalk were redesigned and rewritten from the ground
|
|
up. This allowed us to greatly improve these tools' functionality and
|
|
increase testing for them. The accuracy and output of pt-diskstats was
|
|
enhanced, and the tool was rewritten in Perl. pt-collect was removed and
|
|
its functionality was put into a new, enhanced pt-stalk. pt-stalk is now
|
|
designed to be a stable, long-running daemon on a variety of common platforms.
|
|
It is worth re-reading the documentation for each of these tools.
|
|
|
|
The 20 bug fixes cover a wide range of problems. The most important are
|
|
fixes to pt-table-checksum, pt-iostats, and pt-kill. Apart from pt-diskstats,
|
|
pt-stalk, and pt-collect (which was removed), no other tools were changed
|
|
in backwards-incompatible ways, so it is worth reviewing the full changelog
|
|
for this release and upgrading if you use any tools which had bug fixes.
|
|
|
|
Thank you to the many people who reported bugs and submitted patches.

v2.0.1 released 2011-12-30
|
|
==========================
|
|
|
|
The Percona Toolkit development team is proud to announce a new major version:
|
|
2.0. Beginning with Percona Toolkit 2.0, we are overhauling, redesigning, and
|
|
improving the major tools. 2.0 tools are therefore not backwards compatible
|
|
with 1.0 tools, which we still support but will not continue to develop.
|
|
|
|
New in Percona Toolkit 2.0.1 is a completely redesigned pt-table-checksum.
|
|
The original pt-table-checksum 1.0 was rather complex, but it worked well
|
|
for many years. By contrast, the new pt-table-checksum 2.0 is much simpler but
|
|
also much more efficient and reliable. We spent months rethinking, redesigning,
|
|
and testing every aspect of the tool. The three most significant changes:
|
|
pt-table-checksum 2.0 does only --replicate, it has only one chunking algorithm,
|
|
and its memory usage is stable even with hundreds of thousands of tables and
|
|
trillions of rows. The tool is now dedicated to verifying MySQL replication
|
|
integrity, nothing else, which it does extremely well.
|
|
|
|
In Percona Toolkit 2.0.1 we also fixed various small bugs and forked ioprofile
|
|
and align (as pt-ioprofile and pt-align) from Aspersa.
|
|
|
|
If you still need functionalities in the original pt-table-checksum,
|
|
the latest Percona Toolkit 1.0 release remains available for download.
|
|
Otherwise, all new development in Percona Toolkit will happen in 2.0.

v1.0.1 released 2011-09-01
|
|
==========================
|
|
|
|
Percona Toolkit 1.0.1 has been released. In July, Baron announced planned
|
|
changes to Maatkit and Aspersa development;[1] Percona Toolkit is the
|
|
result. In brief, Percona Toolkit is the combined fork of Maatkit and
|
|
Aspersa, so although the toolkit is new, the programs are not. That means
|
|
Percona Toolkit 1.0.1 is mature, stable, and production-ready. In fact,
|
|
it's even a little more stable because we fixed a few bugs in this release.
|
|
|
|
Percona Toolkit packages can be downloaded from
|
|
http://www.percona.com/downloads/percona-toolkit/
|
|
or the Percona Software Repositories
|
|
(http://www.percona.com/docs/wiki/repositories:start).
|
|
|
|
Although Maatkit and Aspersa development use Google Code, Percona Toolkit
|
|
uses Launchpad: https://launchpad.net/percona-toolkit
