Release Notes

All notable changes to this project will be documented in this file.

2.2.0 (27.05.2022)

Fix a major performance bug of the delivery transaction in the JPA-based (PostgreSQL) implementation
Upgrade Gradle to 7.4.2, update some dependencies and improve main build script

Rework security implementation
- Define actual user roles, privileges, and mapping between these two concepts
- Add the concept of a role to the employee model construct; every employee now has a single role
- Improve the the UserDetailsService base class
- Increase security granularity by securing the transaction API endpoints with a different privilege than the resource API endpoints
Rework the transaction API
- Use resource-based paths instead of transaction names
- Improve request structure (combination of path parameters, request parameters, and request body content instead of sending everything as part of the body)
- Add proper Swagger-based API documentation
- Remove requirement for actual server implementations to add a copy+paste transaction controller implementation

Split the project into multiple modules in order to increase flexibility and extensibility of the benchmark:
- wss-commons: Commonly used utilities
- wss-data-gen: Generic data generator for creating a set of data for initial database population
- wss-server-core: Defines the core features of the WSS benchmark server, including API, security, services, and data transfer objects
- wss-server-jpa-pg: Actual implementation of the server using JPA-based persistence and a PostgreSQL DBMS
- wss-server-ms-jacis: Actual implementation of the server using MicroStream-based persistence and JACIS for concurrent data access management
Add a second MicroStream-based implementation using Java locks and synchronization features for concurrent data access (wss-server-ms-sync)
Various other minor changes and improvements
Improve configurability of JMeter script
Improve documentation
