The top level API module for NoSQLBench. This module should have no internal module dependencies other than the mvn-default module. All modules within NoSQLBench can safely depend on this module with circular dependencies. This module provides cross-cutting code infrastracture, such as path utilities and ways of describing services used between modules. It is also the transitive aggregation point for system-wide library dependencies for logging and testing or similar needs.

There is a newer version: 5.17.0
