event-store-commons

Defines a common event store Java interface and provides some adapters (like for Greg Young's event store) and implementations (like in-memory or file-based).

Versions

• 0.5.x (or later) = Java 11 with new jakarta namespace
• 0.4.x = Java 11 before namespace change from 'javax' to 'jakarta'
• 0.3.2 (or less) = Java 8

Caution: The code coverage value is not correct (it's actually higher than above value) as the 'test' module is not considered correctly (See Issue #4)
