Worked on the ClickHouse/clickhouse-docs repository to improve the accuracy of technical documentation related to the MergeTree storage engine. Focused on correcting the documented threshold for the 'too many parts' exception, updating the value from 600 to 252 to match the actual system behavior. Used Markdown and technical writing skills to ensure the documentation reflected the current codebase, reducing the risk of user confusion and support overhead. The work involved careful analysis of system limits and precise, traceable edits, contributing to clearer onboarding for new users and maintainers. No code changes were required beyond the documentation update.
