Alex Khatskevich updated the aiven/aiven-docs repository to clarify service plan downgrade rules for Aiven for ClickHouse, focusing on improving documentation accuracy and user guidance. Using Markdown and documentation best practices, Alex revised the downgrade policy to specify that reducing nodes is only possible by switching from Business to Startup on a running service, not by forking to a smaller cluster. This update aligned the documentation with actual product capabilities, reducing ambiguity and potential support queries. The work demonstrated careful collaboration with product teams and contributed to more consistent, user-friendly documentation, supporting smoother onboarding and reducing customer confusion around service plan changes.
