Netty Reviews and Details

Is Netty good?

Social recommendations and mentions

• New scalable, fault-tolerant, and efficient open-source MQTT broker

  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 / almost 2 years ago

• Modern Async Primitives on iOS, Android, and the Web

  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 / almost 2 years ago

• Lessons learned from picking a Java driver for Amazon ElastiCache for Redis - Part 2

  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 / over 2 years ago

• what does this error mean

  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 2 years ago

• How to invite friends in java?

  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: almost 3 years ago

• Is java the right language for high throughput, low latency web servers?

  Yes - look at the Netty project for an example of "low latency" Java network development - the language is not the limiting factor. Source: almost 3 years ago

• Possibly stupid question, is java the right language for low latency and high throughput web servers?

  As you are in i/o tasks, you can look at spring webflux / microprofile / quarkus. If you mature enough netty (https://netty.io/) based solution will be more effecient. Source: almost 3 years ago

• I want to create a solution with users and admins - they would communicate over sockets via an intermediate server. What is the best way to implement this in Java?

  Look into Netty which is a NIO client server framework. Source: about 3 years ago

• ShardingSphere-Proxy Front-End Protocol Troubleshooting Guide and Examples

  In the ShardingSphere-Proxy front-end Netty decoding logic, when a data Packet of length 0xFFFFFF is encountered, the Payload part of multiple MySQL Packets is aggregated via CompositeByteBuf. - Source: dev.to / about 3 years ago

• P2P Game with UDP Networking - What library do I use?

  I've taken a look at Kryonet and Netty, but they seem to only be for client-to-server models (Correct me if I'm wrong). Source: about 3 years ago

• Libraries other than Spring Boot for creating web APIs

  One approach I do not think many consider is starting with the Netty, which is used by many frameworks. We ended up using this for our current product, and while this gives the ultimate flexibility in handling requests it also heightens the bar somewhat for the ones employing its use, as it just gives you the nuts and bolts and it is up to you to make it play nice for your use-cases. I had to write quite a few... Source: over 3 years ago

• Apache ShardingSphere -Proxy Performance with PostgreSQL is Improved 26.8% with Version 5.1.0

  Since 4.1.50.Final, Netty’s Epoll has been available in Linux environments with aarch64 architecture. Under an aarch64 Linux environment, compared to Netty NIO API, performance can be greatly enhanced with the use of Netty Epoll API. - Source: dev.to / over 3 years ago

• Spring Micronaut or Spring Reactive

  Have a read over at https://spring.io/reactive It's really if you like the spring way of doing things or go with Micronaut. Both cases you are running your app on top of Netty which is asynchronous (for more information https://netty.io/) instead if a traditional application server such as jetty, tomcat, glassfish etc. Source: over 3 years ago

• Golang’s most important feature is invisible

  Java offers netty (https://netty.io/) which excels at developing custom protocol clients and servers. Source: over 3 years ago

• Jodd – The Unbearable Lightness of Java

  We looked around since we wanted to move off Tomcat and decided on Netty: https://netty.io/ I'm not on the engineering team so can't speak to the cost/benefit, but it seems to have been a pretty successful transition. - Source: Hacker News / over 3 years ago

• Appwrite 0.12 - A major milestone for the open source Firebase Alternative

  For example, you could have opted to do this in Kotlin and use a pleathora of rock-solid backend servers as a base, like Netty. Not only the latter is better at handling (large amounts of) concurrent requests, memory management, security, but it'll beat PHP at any test you through at it. Source: over 3 years ago

• How Linkerd retries HTTP requests with bodies (using hyper, bytes, and http-body!)

  In most other programming languages, this problem would also be solved with reference counting, or with tracing garbage collection. In Java, for example, the Netty asynchronous networking library also provides similar reference counted byte buffers. It's interesting to note that these byte buffers are also reference-counted, despite Java implementing tracing GC. This is because reference-counting tends to perform... Source: almost 4 years ago

• Good resource for learning websocket?

  And you should be good, now if you want pure hardcore stuff, try reading the websocket doc of netty.io, an overpowered network framework, it’s how I’ve learned that subject and I definitely not recommend it. Source: about 4 years ago

• How do you make open ports secure?

  My friend is making a simple card game using netty to allow online play (he is making this to play with relatives). He is very worried about having an open port. Is there a way to make sure that the open port will only accept data from his program? Is there any risk of doing this without any security? Source: about 4 years ago

• What is the best java library for networking?

  Netty is a really fast library, but it is a pain to use sometimes. Also, you have to do a lot of the work yourself. Source: about 4 years ago
