Project

Hyperledger Caliper

Project Health

  • The core code-base continues getting cleaner and more modular. The goal is to make many of the internal features behave like plugins, following a general schema. Based on this approach, contributors can easily add new features in a well-defined, localized manner, without being familiar with the entire code-base.
  • The documentation pages are also being improved to provide hands-on tutorials about setting up Caliper with well-known examples of different DLTs.
  • Community relations mainly happen on Rocket.Chat, and the questions are answered in detail, and on time. Furthermore, there is an increasing contributor/user interest related to the supported DLTs (Besu, Ethereum, Fabric v2).

Questions/Issues for the TSC

There are no issues at this time.

Releases

  • v0.3.2 patch was released addressing the Fabric v2 support
  • v0.4.0 is coming soon

Overall Activity in the Past Quarter

  • Project stats (since the last report)
    • Issues closed: 58
    • PRs merged: 79
  • Development-related 
    • Keeping up with Fabric 2.x releases
    • User workload module improvements (OO approach), with further incoming updates/smart features to help users write concise benchmark logic
    • Terminology changes/consolidations (adapter→connector, master→manager, callback→workload module, using "contract" everywhere)
    • Simplify the SUT connector API. Hopefully, this will make the implementation of new connectors and maintenance of current connectors easier.
    • Messaging between processes has been updated (messenger modules are pluggable now, explicit message classes added for transport-agnostic message handling).
    • Some modules have been made event-oriented, to loosen the coupling with other modules. 

Current Plans

v0.4.0 will contain a major code-base cleanup, address the followings:

  • Identify the parts of the code-base that fit the description of a "plugin" (like performance and resource monitors in the manager process, TX observers in the worker processes).
  • Make such plugins as object-oriented as possible, following strict interfaces and life-cycle management.
  • Streamline data flow in/between the Caliper processes and modules, thus simplifying the code-base and improving performance and robustness. 

Subsequent releases will target the improvement of platform supports, starting with the existing adapters.
