Worked on the oracle-japan/ocitutorials repository to update documentation and branding for MySQL HeatWave, focusing on content management and technical writing using Markdown. The main feature involved rebranding all references from MySQL Database Service to MySQL HeatWave across tutorials and top-page content, ensuring consistency and clarity for users. Added a comprehensive product description that explains HeatWave’s cluster architecture, in-memory store, columnar data support, integrated ML/LLM, and its capabilities for OLTP, OLAP, ML, and vector search workloads. All changes were tracked through clear, traceable commits, emphasizing maintainable documentation practices and accurate representation of product features for end users.
