PROFILE
Matthias Oesterheld
Contributed to the Graylog2/graylog2-server repository by delivering stability, security, and maintainability improvements across backend systems. Focused on Lucene integration, the work replaced shaded OpenSearch Lucene dependencies with standard Lucene classes, introduced backward compatibility for older index formats, and enforced stricter API usage. In subsequent efforts, enhanced certificate management by strengthening chain validation, key handling, and cryptographic practices, while also improving cluster event reliability and system notifications. Leveraged Java, Lucene, and Mockito to refactor code, optimize performance, and increase test robustness. The approach emphasized risk mitigation, production readiness, and compliance, resulting in more secure and maintainable backend infrastructure.

Feb 1, 2025February 2025: Graylog2/server Lucene integration stability and backward compatibility enhancements. Focused on removing shaded OpenSearch Lucene dependencies, enabling standard Lucene usage, implementing governance around Lucene usage, and providing a path to support older index formats. Key deliveries include migrating away from shaded Lucene classes, introducing lucene-backward-codecs, expanding forbidden API checks, and refactoring index input handling to leverage Lucene FSDirectory with a custom InputStreamIndexInput.
