Step-by-Step Solution
Solution:
Step 1: Understand shared libraries in mono-repos
Shared libraries are centrally managed and used by all services in the mono-repo.Step 2: Analyze impact of update
All microservices will use the updated library after the next build is correct because all services referencing the library will use the updated version after rebuilding. Only the microservice where the change was made will use the updated library is false as the library is shared. The update will cause all microservices to be rebuilt automatically may happen depending on CI but is not guaranteed. The shared library update will not affect any microservice until manually integrated is incorrect.Final Answer:
All microservices will use the updated library after the next build -> Option BQuick Check:
