Worked on enhancing the Aiven for ClickHouse documentation within the aiven/aiven-docs repository by clarifying TLS security requirements. Focused on technical writing and documentation skills, the update removed ambiguous language around the term '(plaintext)' to improve accuracy and reduce the risk of security misconfigurations. The approach emphasized clear, security-focused wording and ensured traceability for easier audits and reviews. Markdown was used to implement these changes, resulting in more precise guidance for customers configuring TLS connections. This work addressed potential misunderstandings, lowered support friction, and contributed to the overall reliability of the documentation without introducing new features or bug fixes.
