gorums

license GoDoc Travis Build Status golangci-lint

Gorums [1] is a novel framework for building fault tolerant distributed systems. Gorums offers a flexible and simple quorum call abstraction, used to communicate with a set of processes, and to collect and process their responses. Gorums provides separate abstractions for (a) selecting processes for a quorum call and (b) processing replies. These abstractions simplify the main control flow of protocol implementations, especially for quorum-based systems, where only a subset of the replies to a quorum call need to be processed.

Gorums uses code generation to produce an RPC library that clients can use to invoke quorum calls. Gorums is a wrapper around the gRPC library. Services are defined using the protocol buffers interface definition language.

System Requirements

To build and deploy Gorums, you need the following software installed:

  • Protobuf compiler (protoc)
  • Make
  • Ansible (used by benchmark script)

Contributors Guide

We value your contributions. Before starting a contribution, please reach out to us by posting on an existing issue or creating a new one. Students and other contributors are encouraged to follow these guidelines:

  • We recommend using VSCode with the following plugins
    • Go plugin with the
      • gopls language server enabled
      • golangci-lint enabled
    • Code Spell Checker
    • markdownlint
    • vscode-proto3
  • Code should regularly be merged into master through pull requests.
