Timothy,

We did not plan it for 5.0 release.
But you can contact us http://www.percona.com/contacts.html
to discuss if you want this fix in 5.0.

Any idea if the bugfix for 49047 will be merged into the 5.0 release? We’re running percona highperf 5.0.84 version currently and getting bitten by this bug occasionally during high concurrency updates to a single row. (UPDATE blah set foo=foo+1 where id=12345;)

Are you guys planning on updating your rhel builds to include 9.1? Seems the MySQL-percona builds are still on XtraDB 9.

Wow! That’s a really good work taskforce! Congrats to all Percona guys!

Just putting here my opinion..

About the ‘Support of different pagesizes ( 4K, 8K, 16K)’, wouldn’t be a good idea to make some benchmarks based on file-system partitioning tuning/tweaking like I posted sometime ago? http://www.mysqlperformanceblog.com/2010/02/28/maximal-write-througput-in-mysql/#comment-730851

Hi,
I’m testing this release on redhat5 64bits and so far the performance gain from a vanilla 5.0 is roughly 10x, I’m very impressed, thx a lot for the work done. One thing I can not get to work is the INDEX_STATISTICS table and the TABLE_STATISTICS one, the USER_STATISTICS is running fine after setting the userstat_running global variable ON but the other 2 tables are still empty. Is this working on this release?

(Server version: 5.1.43-51-log Percona SQL Server (GPL), XtraDB 9.1, Revision 57)

btw. we are planning to go in production with this release for bligoo.com (5.5 million visitors/month)

king regards,
Emilio

Than you for your work – we are using it now on magentocommerce.com and speed improvement is really great. Also, query profiling and debugging is much easer then with vanilla MySQL.

Actually bugfix (patch proposed by Harrison Fisk ) for http://bugs.mysql.com/bug.php?id=49047
is already in next bugfix release of XtraDB, and will be available to download soon.

That change is in the Facebook patch but I do not think it is needed after the fix for http://bugs.mysql.com/bug.php?id=49047
