The mysql> command-line prompt is iconic, shown in countless documentation pages, forum posts, tutorials and manuals. It’s immediately identifiable – one look, and you immediately know the context in which commands are being executed. So it’s only with good reason that we would consider changing the prompt value to something else, and Daniël van Eeden provided a compelling suggestion to modify this to provide user, host and database context. Because the mysql prompt is user-configurable, this is easy to do dynamically:

mysql> prompt something>
PROMPT set to 'something> '
something> select 1;
+---+
| 1 |
+---+
| 1 |
+---+
1 row in set (0.00 sec)

something>

With Analyst for MySQL, you will be able to get your hands on hundreds of metrics within moments. It really takes all of the guesswork, as well as tedious long sessions of writing queries out of managing a MySQL database server.

Cross-Platform

Not only can you run the program on Windows, Mac, or Linux, you can also generate server reports from each of those platforms as well! No need to install anything on the server at any time. All diagnostics are run from your laptop or desktop machine. The …

I wrote a guest post for High Scalability about how we scale our backend systems at VividCortex. It’s heavy on MySQL, sprinkled with a little bit of Redis’s magic pixie dust, and Kafka is also a key part of the architecture.

Important takeaways:

• Our workload is unusual in that some use cases require reading huge amounts of data with interactive response times. We have lots of time-series data, but not a typical time-series workload.
• Our data distribution is also weird.
• Read optimization is vital, but we are extremely write-heavy.
• We’re sharded and partitioned.
• We run our systems on just a few low-end EC2 machines.
• Go is a huge part of our speed to market and cost efficiency.
• We use a “just enough micro-” …
