cherami-server Build Status Coverage Status

Cherami is a distributed, scalable, durable, and highly available message queue system we developed at Uber Engineering to transport asynchronous tasks.

This repo contains the source code of Cherami server, cross-zone replicator server, and several tools. Your application needs to use the client to interact with the server. The client can be found here.

Getting started

To get cherami-server:

git clone git@github.com:uber/cherami-server.git $GOPATH/src/github.com/uber/cherami-server


We use glide to manage Go dependencies. Please make sure glide is in your PATH before you attempt to build.

  • Build the cherami-server and other binaries (will not run test):
make bins

Local Test

We need a Cassandra running locally in order to run the integration tests. Please make sure cqlsh is in /usr/local/bin, and it can connect to the local Cassandra server.

make test

Run Cherami locally

  • Setup the cherami keyspace for metadata:
RF=1 ./scripts/cherami-setup-schema
  • The service can be started as follows:
CHERAMI_ENVIRONMENT=local ./cherami-server start all

Note: cherami-server is configured via config/base.yaml with some parameters overriden by config/local.yaml. In this config, Cherami is bound to localhost.

One can use the CLI to verify if Cherami is running properly:

./cherami-cli --env=prod --hostport= create destination /test/cherami

Deploy Cherami as a cluster

Documentation coming soon....


We'd love your help in making Cherami great. If you find a bug or need a new feature, open an issue and we will respond as fast as we can. If you want to implement new feature(s) and/or fix bug(s) yourself, open a pull request with the appropriate unit tests and we will merge it after review.
