Playing with TokuDB updates I noticed in SHOW PROCESSLIST unsual for MySQL State.
(Do not look in stupid UPDATE query, it's just for testing )
So looking in SHOW PROCESSLIST you can see progress of query execution.
I would want to see it in standard MySQL and InnoDB more than all these triggers and stored routines! Probably will implement this in XtraDB.

Many people in the Apache Hadoop community have asked Yahoo! to publish the version of Apache Hadoop they test and deploy across their large Hadoop clusters. As a service to the Hadoop community, Yahoo is releasing the Yahoo! Distribution of Hadoop -- a source code distribution that is based entirely on code found in the Apache Hadoop project.
This source distribution includes code patches that they have added to improve the stability and performance of their clusters. In all cases, these patches have already been contributed back to Apache, but they may not yet be available in an Apache release of Hadoop.
Dear community,
We are pleased to announce the build16 of MySQL server® with Percona patches.
Since the build13 there was a couple of customer specific releases, which explains cutover in numbering and a pause between the builds. Also we prepared build for both 5.0.77 and 5.0.82 versions.
Since that time new patches were added:
This patch adds information from SHOW PROFILE to query information in slow.log output.
profiling_server. This variable ( ON / OFF ) enables profiling of all queries (in all connections).
profiling_use_getrusage. This variable ( ON / OFF ) enables usage of getrusage function in profiling.
Be careful, enabling profiling_server may cause performance degradation, especially with profiling_use_getrusage.
innodb_extra_rsegments. The number of extra user rollback segments created when new db is created.
New information_schema table innodb_rseg shows information about all rollback segments
This patch provides the configuration variable backport from MySQL 5.4.
Fixed bugs:
