Worked on the dpc-sdp/tide_core repository to enhance the audit workflow for Elasticsearch by refactoring the tide:search-audit-nodes command. The approach involved reducing the node query batch size from 1000 to 500 and disabling access checks during node retrieval, ensuring broader audit coverage and improved compatibility with Elasticsearch constraints. This update increased audit throughput and reduced the risk of missing relevant nodes. The work demonstrated technical proficiency with PHP, Drush, and Search API, focusing on performance optimization and CLI tooling. The changes addressed specific Elasticsearch limitations, resulting in a more reliable and efficient audit process within the Tide Core environment.
