Percona-XtraDB-9.1: released and new coming features

Март 18th, 2010

Recently Alexandr announced new Percona-XtraDB-9.1 release, and now it is good time to summarize features we have and what is expected soon.

This release contains long waited features from 5.0:

  • extended slow.log
  • USER/TABLE/INDEX/CLIENT_STATISTICS + THREAD_STATISTICS

Extended slow.log is now even more extended, there is additional information for each query:

CODE:
  1. # Bytes_sent: 4973  Tmp_tables: 1  Tmp_disk_tables: 1  Tmp_table_sizes: 7808

That is you can see how many bytes was returned by query, was temporary table used,
was it disk table or in-memory, and how big was temporary table.

Also you can profile each individual query from stored procedures, so now you should not
guess what took so long in stored procedure.

What we are working on right now is:

  • InnoDB pagesize, so you will be able to specify 4K, 8K, 16K pagesize when you created database
  • InnoDB fast checksums, idea and implementation was taken from Facebook patches
  • InnoDB big log files ( bigger 4GB). As our benchmarks on FusionIO shows, you may need
    4GB+ log files to get more performance on fast storage systems
  • SHOW TEMPORARY FILES, patch from Venu Anuganti
  • INFORMATION_SCHEMA.SYS_TABLES and SYS_INDEXES to show internal InnoDB data dictionary

Full list of XtraDB engine features (what makes it different from InnoDB-plugin) on the state as it is right now:

Performance improvements

  • Improved buffer_pool scalability
  • Fast recovery
  • Improved IO path
  • Improved rollback segment scalability
  • Separate purge thread
  • Limited size of data dictionary in memory
  • Increased number of concurrent write transactions (undo slots) ( up to 4000 )
  • Fast checksums ( in release process )
  • Support of different pagesizes ( 4K, 8K, 16K) ( in release process )

Usability / operations

  • Show content of buffer_pool
  • Import / export of dedicated tables
  • Import / export of buffer_pool
  • Transactional replication
  • Show internal InnoDB data dictionary
  • Show InnoDB locking/io profiling in slow.log

I hope you enjoy our work!

Январь 22nd, 2010
If you have seen the following error on the Perf Report tab “Message: SimpleXMLElement::__construct()…” – it has been fixed in revision 281. This only affects alerts 11 and 12 so you might not run into it immediately. The solution is to either remove lines “586, 590, 639, 650″ from the bin/kontroll-reporter-5.0.x_linux-x86-2.0.1.pl file, or to run [...]

Kontrollbase rev-158 available

Сентябрь 4th, 2009

This comes rather quickly as the last revision – 150 was just uploaded a few days ago. This is because there was a new method of checking config options in the bin/ scripts that utilizes the codeigniter config files instead of config.cfg in the base directory, the problem was the all of the required bin/ files were updated to this new method except for the alerter script. This was mentioned in bugtrack issue #48 and subsequently fixed this morning. So you can either download the new version which has some other nice fixes or just fix the one file. As usual the download can be had from the download page.

If you choose to just fix the one file you will need to change the following code in bin/kontroll-alerter-5.0.x_linux-x86-2.0.1.pl – here is a link to the diff of the two files.
New function
sub config_connect {
my $cfgapp = "../system/application/config/bin-read-configs.php";
$mysql_r_user = `php $cfgapp read username`;
$mysql_r_pass = `php $cfgapp read password`;
$mysql_r_db = `php $cfgapp read database`;
$mysql_r_host = `php $cfgapp read hostname`;
$mysql_w_user = `php $cfgapp write username`;
$mysql_w_pass = `php $cfgapp write password`;
$mysql_w_db = `php $cfgapp write database`;
$mysql_w_host = `php $cfgapp write hostname`;
$error_log = "../system/logs/sys_error.log";
$debug_log = "../system/logs/sys_debug.log";
}

And then at the very bottom of the script change this simple line:
config_connect($config);
To
config_connect();
