cherami-server

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 [email protected]:uber/cherami-server.git $GOPATH/src/github.com/uber/cherami-server

Build

We use glide to manage Go dependencies. Additionally, we need a Cassandra running locally in order to run the integration tests. Please make sure glide and cqlsh are in your PATH, and cqlsh can connect to the local Cassandra server.

• Build the cherami-server and other binaries:

make bins

Run Cherami locally

• Setup the cherami keyspace for metadata:

./scripts/cherami-setup-schema

• The service can be started as follows:

CHERAMI_ENVIRONMENT=laptop CHERAMI_CONFIG_DIR=`pwd`/config CHERAMI_STORE=/tmp/store ./cherami-server start all

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

./cherami-cli --hostport=<localIP>:4922 create destination /test/cherami

Deploy Cherami as a cluster
