Chariots shared log for Go

gochariots

Scalable shared log Chariots implemented in Go. For the system details, please refer to the EDBT paper: Chariots : A Scalable Shared Log for Data Management in Multi-Datacenter Cloud Environments

Using Docker

If you are seeing this page on Docker repository page, please see this page for details.

Quickstart

We can use Docker Compose to run a local shared log, or Docker Swarm to run a cluster on multiple hosts. Please see this document for detail.

Appending record

To append to the shared log, send POST request to http://localhost:8080/record. The payload needs to be in JSON format. See post_example.sh and example.json.

Issues (TODO)

When a component of any stage stops working and the controller couldn't connect to it, the controller should prompt a warning message rather than just panic.

Design discussion

• Currently sender(propogation) is bundled with maintainer. This eliminate the communication between sender and maintainer, but can't be scaled. If seperate them, sender can be scaled independently, but require extra communication.
• Does token need to carry all records with unsatisfied dependencies? Currently it does that.
