Performance is the key focus. A design goal for Aeron is to be the highest throughput with the lowest and most predictable latency of any messaging system. Aeron integrates with Simple Binary Encoding (SBE) for the best possible message encoding and decoding performance. Many of the data structures used in the creation of Aeron have been factored out to the Agrona project.

libsignal is the foundational cryptographic library that implements the Signal Protocol and other essential primitives used across the official Signal clients and servers, enabling secure end-to-end encrypted communication. Written primarily in Rust with bindings and APIs surfaced for Java, Swift, and TypeScript, this library encapsulates critical algorithms like the Double Ratchet, prekey mechanisms, secure key storage, and zero-knowledge group primitives, along with additional utilities...

Apache RocketMQ is a distributed messaging and streaming platform with low latency, high performance and reliability, trillion-level capacity and flexible scalability. Messaging patterns including publish/subscribe, request/reply and streaming. Financial grade transactional message. Built-in fault tolerance and high availability configuration options base on DLedger. A variety of cross language clients, such as Java, C/C++, Python, Go.

LMAX aims to be the fastest trading platform in the world. Clearly, in order to achieve this we needed to do something special to achieve very low-latency and high-throughput with our Java platform. Performance testing showed that using queues to pass data between stages of the system was introducing latency, so we focused on optimising this area. The Disruptor is the result of our research and testing. We found that cache misses at the CPU-level, and locks requiring kernel arbitration are both extremely costly, so we created a framework which has "mechanical sympathy" for the hardware it’s running on, and that’s lock-free. ...

AREDIS (Asynchronous REDIS java client) is a java client for the Redis Cache server (http://redis.io) designed for performance and efficiency. It has only one connection to each server and uses pipelining for performance rather than connection pooling. It uses the Java 7 NIO based Asynchronous channel API for socket communication to the Redis server. Important features are Data Handler API for storing Objects, OPTI_JAVA_HANDLER for efficient storage of Java Objects, built-in gzip compression, subscribe API for messaging, support for Lua scripts, key hash based sharding, Future results for use in regular synchronous applications, connection pool for Redis transactions using WATCH and auto closing of idle connections.

In fact OkDownload is FileDownloader2, which extends all benefits from FileDownloader and beyond. FileDownloader framework is not easy to write unit-test, it is not a testable framework, so it is not stable enough. The core library of FileDownloader is too complex and not pure enough, so 6K+ star 1K+ fork with around 10 PR. Unit test coverage is very high which means reliable. Simpler interface. Task priority support. Uri file to store output-stream. The core library is Pure and light. More...

With all of the hoopla over Web Services, you would think that servicing user requests over HTTP was something new. While we all may have lots of experience with REST, JSON, XML, SOAP, WSDLs, HTTPS, and even EDI ... but at the end of the day, it all comes down to legacies, security, and performance? So while big companies might have billions of dollars to spend re-writing their back end web legacies, those of us who want to seamlessly automate a simple set of CRUD operations to our...
