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

/**
 * OpConfigErrors are {@link BasicError}s which are known to occur when
 * there is an invalid set of configuration details for an op. This can
 * occur when the user-provided op template data (such as from YAML)
 * is being inspected by a driver adapter to synthesize operations
 * (or functions which know how to do so).
