Securing User Account Details with MySQL
Employee_Team +0 Vote Up -0Vote Down

Keeping user account details secure is always at the forefront of a Database Administrator's mind. However, users want to get up and running as soon as possible without complex login procedures.

You can learn more about this and many other topics in the MySQL for Database Administrator course.

For example, MySQL 5.6.6 introduced a new utility: mysql_config_editor, which makes secure access via MySQL client applications much easier to establish, while still providing a good measure of security.

The mysql_config_editor stores a user's authentication details in an encrypted login file called mylogin.cnf. This login file is readable and writable for the user who invokes the utility, and

Cleanup a MySQL Schema
+0 Vote Up -0Vote Down

My students required way to remove all their tables, views, and constraints from a MySQL database (or the alias schema). Since they’re using referential or foreign key constraints, I also wrote one procedure to drop all foreign key constraints from a database. There’s also another to drop views. The final stored procedure calls the procedure that drops foreign keys, then calls the procedure to drop views before dropping all the tables.

Here’s the dropForeignKeys stored procedure:

Enhancing pt-kill to Better Protect your Servers
+2 Vote Up -0Vote Down
I believe in automation as much as possible, and I'm always working to make the day to day tasks of operations as smooth as possible.  Also I try not to be afraid to take good tools and make them better.

Here in Database Ops at Box, we use pt-kill running as a service to constantly monitor our servers and help protect against long running queries.  But our thresholds are pretty generous, and in some cases it's possible for unforeseen circumstances to cause enough queries to storm the database such that we can have problems before any of them hit the threshold for "busy time."  Ditto for idle connections.

The response is that someone has to be available to manually run another copy of pt-kill with much lower thresholds to clear out these thundering herds.  But what if we could let pt-kill handle both the "normal" mode and still protect

    Efficient Partial Table Scans
    +0 Vote Up -0Vote Down
    There's a pretty common MySQL recipe for performance that if you want to efficiently scan through lots of rows in small chunks that LIMIT with OFFSET is right out.  Using OFFSET, MySQL will have to scan all the rows until it finds the starting position before it starts reading results to return.   Just to be clear, these statements look like:

    SELECT id FROM foo ORDER BY id LIMIT 10 OFFSET 1000;

    If you were trying to read all rows in table then this would  be a very slow and expensive way to do that (in terms of MySQL resources.) The most common optimization is to switch to an algorithm where you remember the last highest id value for each chunk of rows, and then add that to the WHERE clause.

    SELECT id FROM foo WHERE id > 100000  ORDER BY id LIMIT 10;

     This would be a much more efficient way
