Пару лет назад проблему удаления персональных данных из неизменяемого Event Sourcing лога событий по требованию GDPR освещал Mathias Verraes, и предложил два подхода:

"Eventsourcing Patterns: Forgettable Payloads. Store the sensitive payload of an event in a separate store to control access and removal." by Mathias Verraes
- https://verraes.net/2019/05/eventsourcing-patterns-forgettable-payloads/

"Eventsourcing Patterns: Crypto-Shredding. Encrypt sensitive information in an event and delete the key." by Mathias Verraes
- https://verraes.net/2019/05/eventsourcing-patterns-throw-away-the-key/

Проблеме, озвученной Oskar Dudycz, похожее решение дает Mathias Verraes в статье
"Patterns for Decoupling in Distributed Systems: Segregated Event Layers. Explicitly segregate a Bounded Context's events in visibility layers, with their own language."

Тут в чате канала @webkunx подсказывает, что вышел полноценный релиз второго издания "Building Microservices: Designing Fine-Grained Systems" by Sam Newman (September 28, 2021):
- https://www.amazon.com/gp/product/1492034029

Ранее был доступен early release raw & unedited.

Все новинки Software Design & Engineering:

Из них две книги by Vladik Khononov ( @vladik_kh ).

Превосходный пост о роли Ubiquitous Language в Software Design.

Интересная дискуссия по второй ссылке пересылаемого сообщения (диалог Grady Booch и Robert C. Martin). Кстати, Sam Newman тоже не обошел стороной эту тему:

Однако, наблюдая за направлением развития дискуссии, поспешил скорректировать её:

Я думал, что под этим недавним твиттом Gregor Hohpe https://twitter.com/ghohpe/status/1441059739551420421 развернется флейм, но этого не случилось (Возможно, интересней хайповая переписка Буча с дядюшкой Бобом о том, являются ли микросервисы архитектурой или же стратегией развертывания https://twitter.com/Grady_Booch/status/1441871173957001224) Жаль, что не случилось. Тем трудней мне будет отстаивать тему заката интеграции приложений на archdays
