Graeme Rocher - Creator of Grails and Micronaut

ORIGINAL TALK TITLE
Introduction to Micronaut: Lightweight Microservices with Ahead of Time Compilation

ABSTRACT
In this session, the creator of Micronaut and Grails introduces the newly released Micronaut framework and demonstrates how Micronaut’s unique compile-time approach enables the development of ultra-lightweight Microservices for Java. Compelling aspects of the Micronaut framework include:
• Subsecond startup time
• Small processes that can run in as little as 10 MB of JVM heap
• No runtime reflection
• Dependency Injection and AOP
• Cloud Native

Graeme will also demonstrate how you can take your Microservices to the next level by using Micronaut's Ahead of Time Compilation (AOT) support and Oracle's GraalVM [...]

Whats the situation one year after this presentation? Is Micronaut going forward and being adopted?

[abhishes]

Yes. This is fantastic talk and Micronaut looks great. Although I'm very skeptical of GraalVM which might just be an Oracle licensing trap.

[pguti]

Graalvm + micronaut + grails !!!! I want that!!!

[hectortrapeator]

man, do u know of any example to call a stored procedure using micronaut

[MegaLilmaz]

Very nice modern framework.
How popular Micronaut nowadays, if anyone knows?

[timbuethe]

What is he using for switching the SDK in command line? I mean the SDK command?

[TheodoreRavindranath]

Micronaut looks like Dagger 2 with a truck load of goodies!

[ChristosGoros]

Halfway through the demo I could not remember if this was micronaut or quarkus

[jacek]

You've kinda shoot your leg by saying "why switch to Go when it will have all feature Java has, Java will be as fast as Go". Well, why switch to Micronaut, when it will be as mature as Spring, then Spring will catchup with its own native project" :)
BTW we are starting a new service on Micronaut. :) However, two years later and still native-image is broken and definitely does NOT work out-of-the-box outside of toy tutorial projects :(

thumbs down, not The Micronauts i was expecting.
