Description
Performance benchmarking distributed systems (such as DLTs) is a challenging task, comprising of multiple aspects, such as scalable workload generation, representative workload definitions, and comprehensive data analysis.
Hyperledger Caliper is a general-purpose benchmarking tool with the goal of mitigating the aforementioned aspects of performance benchmarking:
- It provides a flexible architecture to allow scalable workload generation.
- It collects and reports results based on detailed client-observable execution traces.
- It allows the implementation/plug-in of custom workload behaviors to meet the diverse criteria of a wide range of business scenarios.
The flexible support of the aforementioned performance benchmarking aspects inherently makes the setup and configuration of a Caliper-based project cumbersome and error-prone:
...
The exact steps of the project are detailed in the Expected Outcome section.
