Worked on refining documentation within the aiven/aiven-docs repository, focusing on clarifying free plan limits and updating time-series database recommendations. Used Markdown to specify PostgreSQL free plan constraints, such as setting max_connections to 20, and removed M3DB from recommended solutions, introducing guidance for AlloyDB Omni and ClickHouse. Anchored updates to concrete commits and tracked them against specific issues for traceability. The documentation improvements aimed to streamline onboarding, reduce user confusion, and align technical guidance with current product capabilities. Emphasized clear communication and version control, leveraging documentation skills to ensure users have accurate, actionable information about available database options.
