## What it is
Cherami is a distributed, scalable, durable, and highly available message queue system developed at Uber for transporting asynchronous tasks. This repository contains the server, cross-zone replicator, and tooling, but the project is deprecated and no longer maintained.

## Use cases
- run a distributed message queue for asynchronous task transport
- replicate messages across availability zones
- self-host a durable publish-subscribe messaging system
- study the architecture of Uber's message queue system

## When to choose
- you need a historical reference implementation of a distributed message queue in Go
- you are researching cross-zone message replication designs

## When to avoid
- you need a maintained message queue for production use
- you want community support, bug fixes, or new features
- you are starting a new project and need a reliable messaging system

## Facets
- artifact type: service
- maturity: abandoned
- function: message-queue, streaming, rpc
- domain: microservices, backend
- platform: go, self-hosted
- tags: deprecated, asynchronous-tasks, cassandra, cross-zone-replication, uber, messaging, linux, docker
