Kafka-style message streaming in Go. Built on NATS. Single binary, no JVM, no ZooKeeper.

A Go library that implements Consistent Hashing with zero dependency

A Go distributed systems development framework

grpc-go is a Go language implementation of the gRPC framework, providing a remote procedure call library for high-performance service communication. It uses the HTTP/2 protocol to execute functions on remote servers as if they were local methods and utilizes protobuf service bindings to generate type-safe client and server code. The project features a bidirectional streaming transport that supports asynchronous, full-duplex message streams between clients and servers. This networking layer allows for various communication patterns, including client-to-server and server-to-client streaming, to

This project is a full-featured BitTorrent client library and protocol implementation. It provides the core components necessary for peer-to-peer file sharing, including a networking stack that supports the BitTorrent specification, tracker communication, and swarm management. A primary differentiator is the inclusion of a virtual filesystem that allows torrents to be mounted as read-only drives. This system enables on-demand content streaming, where specific data pieces are fetched from the network only when a read request occurs, rather than requiring the entire archive to be downloaded fir

A library that implements the outboxer pattern in go

More effective network communication, two-way calling, notify and broadcast supported.

A library built to provide support for defining service health for golang services. It allows you to register async health checks for your dependencies and the service itself, provides a health endpoint that exposes their status, and health metrics.

Dragonboat is a Go implementation of the Raft consensus protocol designed to maintain consistent state across a distributed cluster of nodes. It provides a library for building distributed state machines that ensure data integrity and fault tolerance during system failures. The project distinguishes itself through a multi-group Raft implementation, which partitions data across independent consensus groups to distribute workloads and increase overall system processing capacity. It also incorporates mutual TLS to encrypt inter-node communication and verify the identity of cluster members. The

Glow is an easy-to-use distributed computation system written in Go, similar to Hadoop Map Reduce, Spark, Flink, Storm, etc. I am also working on another similar pure Go system, https://github.com/chrislusf/gleam , which is more flexible and more performant.

dht is used by anacrolix/torrent, and is intended for use as a library in other projects both torrent related and otherwise

Kit is a microservices architectural framework and toolkit for Go. It provides a set of standardized primitives and abstractions for implementing service, endpoint, and transport layers in a decoupled manner. The framework focuses on system instrumentation through integrated distributed request tracing and a service instrumentation toolkit that utilizes counters and gauges to export performance data to external monitoring backends. It includes a structured logging library that records system events as key-value pairs to ensure compatibility with log aggregation tools. The project covers a br

etcd is a distributed key-value store and configuration store designed to maintain a consistent set of data across a cluster of nodes. It functions as a reliable registry for storing and synchronizing critical settings and metadata used by distributed applications. The system implements the Raft consensus algorithm to ensure data consistency and leader election across servers. To protect data transfers and verify node identities, it utilizes a network security layer based on mutual TLS and client certificates. Its capabilities cover distributed configuration management, cluster state synchro

Simplified distributed locking implementation using Redis

go-jump: Jump consistent hashing

ecommerce microservice

Consistent is a Go library that implements consistent hashing with bounded loads to distribute data keys across nodes in a distributed system. It provides a mechanism for mapping keys to cluster members that minimizes data movement during membership changes while preventing performance hotspots. The library distinguishes itself by enforcing strict capacity limits on individual nodes, ensuring that no single member becomes overwhelmed by excessive key assignments. It supports virtual node mapping to distribute physical capacity across the hash ring, allowing for granular control over load bala

Take control of your data, connect with anything, and expose it anywhere through protocols such as HTTP, GraphQL, and gRPC.

A revamped Google's jump consistent hash

Emitter is a distributed pub-sub platform and message brokering system that decouples senders and receivers through topic-based routing. It functions as an MQTT message broker and WebSocket communication server, enabling real-time data exchange between hardware devices and web-based clients. The system acts as a secure channel orchestrator and message persistence engine. It ensures delivery through a storage system that buffers historical messages and queues data for offline subscribers. Access to these data streams is managed via time-limited permission keys that enforce granular read and wr
