redis-canal 0.1.5

redis_canal

redis-canal

Proxy redis stream from one to another through global queue service.

Motivation: Redis provided on the cloud is usually only available within a VPC and does not provide external access. We want to provide a way to synchronize messages across clouds without going through a VPN.

Supported queue service

• AWS SQS

Welcome to contribute more queue service, see adapter/impl for more details.

We also support the plugin system, the adapter can also be imported as a third-party library. See example for more details.

Install

pip install redis-canal[all] for all components.

Or use docker image

docker pull wh1isper/redis-canal

Usage

Use CLI

• redis-canal stream-to-queue to start a daemon to consume redis stream and push to global queue
• redis-canal queue-to-stream to pull from global queue and push to redis stream

CLI args support envvar, which you can refer to envs.py.

TODO

• More adapter for Google PubSub, Kafka, etc
• Allows users to more easily configure the adapter(Now only support environment variables, within Adapter)
