Last spring, we added a feature that allows the user to see the progress of writes in a statement. Vadim liked it. In 2.2.0, in “show processlist”, we add progress information on reads.
Here is an example of what “show processlist” displays on an update:
mysql> show processlist \G
*************************** 1. row ***************************
Id: 1
User: root
Host: localhost
db: test
Command: Query
Time: [...]
