The confusing strategy for MySQL shell

Where the hell is it?

The MySQL shell is a potentially useful tool that has been intentionally made difficult to use properly.

It was introduced, with much fanfare, with the MySQL Document Store, as THE tool to bridge the SQL and no-SQL worlds. The release was less than satisfactory, though: MySQL 5.7.12 introduced a new feature (the X-protocol plugin) bundled with the server. The maturity of the plugin was unclear, as it popped out of the unknown into a GA release, without any public testing. It was allegedly GA quality, although the quantity of bug reports that were filed soon after the release proved otherwise. The maturity of the shell was known as "development preview", and so we had a supposedly GA feature that could only be used with an alpha …

MySQL Shell with Command Completion

MySQL ShellCLI Interfaces are usually boring, ASCII-ish functional interfaces that are as about as exciting as paint drying or end user license agreements for your rice steamer. They get the job done but no excitement. The new MySQL Shell (mysqlsh instead of mysql at the command line is a great new tool but like its predecessor it is not exactly visually dynamic.

Until Now.

At labs.mysql.com there is a new version of the MySQL Shell that adds some new functionality and some visual enticements. I was in a session at Oracle OpenWorld and was impressed by not only the visually stunning upgrade but by the fact that we now get command auto-completion!

You can login as you did with the old shell but then you see that little bit …

Quick and dirty concurrent operations from the shell

Let’s say that you want to measure something in your database, and for that you need several operations to happen in parallel. If you have a capable programming language at your disposal (Perl, Python, Ruby, PHP, or Java would fit the bill) you can code a test that sends several transactions in parallel.

But if all you have is the shell and the mysql client, things can be trickier. Today I needed such a parallel result, and I only had mysql and bash to accomplish the task.

In the shell, it’s easy to run a loop:

for N in $(seq 1 10)
do
mysql -h host1 -e "insert into sometable values($N)"
done

But this does run queries sequentially, and each session will open and close before the next one starts. Therefore there is no concurrency at all.
Then I thought that the method for parallel execution in the shell is to run things in the background, and then collect the …
