Subject:SHOW CREATE TABLE suddenly slow on InnoDB?
View as plain text  
Hey all,

I'm trying to figure out how InnoDB executes a SHOW CREATE TABLE query so I
can figure out what could possibly have made them suddenly slow down?

mysql> SHOW CREATE TABLE `my_table`;
...
1 row in set (37.48 sec)

We tend to execute many of these statements concurrently, but it's never
been a problem until recently. I upgraded the IO subsystem, and our
statistics indicate that it's not maxing out IO (at least IOPS).

This is problematic because the ORM we're using uses that to figure out the
structure of our DB...
