Worked on the PowerDNS/pdns repository to enhance configuration documentation, focusing on clarifying how the main database and shard database sizes can be configured independently. Applied technical writing and documentation skills using reStructuredText to update guidance on LMDB settings, specifically detailing the interaction between lmdb-map-size and lmdb-shards-map-size. This documentation update aimed to reduce the risk of misconfiguration and streamline onboarding for new users by providing clearer, more accurate information. The work demonstrated attention to detail in versioned documentation and careful cross-referencing of related settings, supporting both user understanding and ongoing maintenance of PowerDNS deployments.
