PROFILE
Laura Schanno
Over twelve months, contributed to the NationalSecurityAgency/datawave repository by building and refining backend systems focused on query processing, validation, and infrastructure reliability. Delivered features such as configurable query validation endpoints, Zookeeper-based concurrency control, and time-aware analytics, while modernizing APIs and improving error handling. Applied Java, Maven, and Zookeeper to enhance code maintainability, performance, and developer experience, including public API design for scanner configuration and robust schema validation. Addressed build engineering challenges by stabilizing multi-module Checkstyle integration and improved documentation for onboarding. The work emphasized code quality, extensibility, and operational stability, supporting both business requirements and long-term maintainability.

Jul 1, 2026July 2026 — NationalSecurityAgency/datawave: Focused on build reliability and consistent code quality checks across a multi-module Maven project. Delivered a critical bug fix to Checkstyle config path resolution by prefixing the path with ${maven.multiModuleProjectDirectory}, enabling child modules to locate checkstyle.xml from the project root and preventing file-not-found errors during builds. This stabilizes CI, speeds up feedback, and simplifies maintenance of multi-module configurations.

Jun 1, 2025June 2025 (NationalSecurityAgency/datawave): Delivered a focused UX improvement by clarifying AmbiguousNotRule error messaging. The error now clearly indicates that NOT applies only to the immediately preceding term, reducing confusion in complex query syntax and lowering support overhead. Implemented via targeted refactor and commit 35d560349e88d9edb78606a1d3ab8bd5f9eaa5bf (Update error message from AmbiguousNotRule (#2959)).

Nov 1, 2024November 2024 was focused on stabilizing and modernizing the datawave query core for NationalSecurityAgency/datawave. Key refactors improved content function parsing and API stability, including a consolidation in the query-core module and the introduction of a FieldTerms helper. We removed reliance on non-public Accumulo APIs to reduce fragility and prepared the ground for future enhancements. Additional efforts expanded the query surface and testing; a skeleton validation endpoint was added, multi-field noExpansion support was introduced, a new sum.counts parameter for DiscoveryLogic enables flexible aggregation, and tests were added to validate patterned model mapping in query expansion. These changes collectively improve reliability, performance readiness, and business-ready capabilities for external clients.
