Conc VS Netty

It's a pity Go didn't have structured concurrency: https://vorpus.org/blog/notes-on-structured-concurrency-or-go-statement-considered-harmful/ There's a library for it: https://github.com/sourcegraph/conc But this goes to one of the things I've been kind of banging on about languages, which is that if it's not in the language, or at least the standard... - Source: Hacker News / about 1 month ago

What are possible use cases for this tool? Why would I want to find out the total runtime of all videos in a directory? Also, you might wanna limit concurrency[0] instead of spawning many ffprobe instances at the ~same time.

While virtual threads will be stable in Java 21, Structured Concurrency is still a preview feature. You probably won't see it in production anytime soon. Preview features require a special flag when compiling and running them, and they won't run on newer versions of the JVM. I don't expect to see StructuredTaskScope in common production use before the next LTS version is out. But it doesn't mean you cannot have... - Source: Hacker News / 11 months ago

I'm also a fan of Conc for managing various different concurrency patterns -- don't create manual worker pools for locally distributed tasks if you can use Conc, etc. Source: 11 months ago

I will probably be using more conc too now. Lots of great primitives for dealing with multiple functions returning the same types or errors etc. Source: about 1 year ago

We use Netty (https://netty.io/) as the source of the MQTT communication, and we build the MQTT features the MQTT broker should support ourselves on top of that. - Source: Hacker News / 5 months ago

In this space, we also have the somewhat related term blocking. Java's NIO library is one well-known non-blocking tool used for managing multiple tasks on a single Java thread. When listening to sockets, most of the time a thread is just blocked, doing nothing until it receives some data. So, it's efficient to use a single thread for monitoring many sockets, to increase the likelihood of the thread having some... - Source: dev.to / 6 months ago

Given the fact that Lettuce is built with Netty, we also immediately noticed quite an impact on the initialization time (cold start) of our lambda function. Netty is really fast while executing, but takes a bit of time to initialize. The new Lambda Snapstart functionality might help with that. - Source: dev.to / about 1 year ago

Io.netty or netty.io is a Java network library, so it does stuff with servers (Minecraft's multiplayer, Chrome websites, local programs talking with each other etc.). Source: over 1 year ago

If you're still determined, I'll give you two options: 1. Sockets: A simple but primitive way of transferring and receiving data. Everything has to be done synchronously. 2. Netty: A much more robust and flexible asynchronous networking library, but requires much more boilerplate to get started. Source: over 1 year ago
