Slow MySQL query performance is all too common. Of course it is. A good way to go is, naturally, a dedicated profiler that actually understands the ins and outs of MySQL.

The Jet Profiler was built for MySQL only, so it can do things like real-time query performance, focus on most used tables or most frequent queries, quickly identify performance issues and basically help you optimize your queries.

Critically, it has very minimal impact on your server's performance, with most of the profiling work done separately - so it needs no server changes, agents or separate services.

Basically, you install the desktop application, connect to your MySQL server, hit the record button, and you'll have results within minutes:

DbSchema is a super-flexible database designer, which can take you from designing the DB with your team all the way to safely deploying the schema.

The way it does all of that is by using a design model, a database-independent image of the schema, which can be shared in a team using GIT and compared or deployed on to any database.

And, of course, it can be heavily visual, allowing you to interact with the database using diagrams, visually compose queries, explore the data, generate random data, import data or build HTML5 database reports.

Lots of interesting writeups on Java 9 this week.

Here we go…

1. Spring and Java

>> Concurrency: Java Futures and Kotlin Coroutines [frankel.ch]

A comprehensive and practical comparison of experimental Kotlin Coroutines and Java Futures.

>> JCP EC Votes against the Java Platform Module System [infoq.com]

The state of Jigsaw going forward will certainly be interesting to keep track of after the vote this week.

>> JDK 9 Checklist: Project Jigsaw, sun.misc.Unsafe, G1, REPL, and More [takipi.com]

Another write-up going through most important changes coming up with the Java 9.

>> How to Run Multiple Versions of All Your Dev Tools with Jenv [sitepoint.com]

Jenv allows you to install and manage several versions of Java-based applications so maintaining a few versions of the same app side by side should not be a problem anymore – very cool.

>> Java SE 9 – JPMS automatic modules [joda.org]

Automatic modules are supposed to be a solution to the problem of migrating existing code to the new modular ecosystem – but there are situations where it might not work flawlessly.
