PROFILE
Matt Burgess
Over eight months, contributed to the apache/nifi repository by delivering features and fixes that enhanced security, flexibility, and reliability in data processing workflows. Work included upgrading core dependencies for improved compliance, adding dynamic database connectivity in Groovy-scripted processors, and implementing flow analysis rules to detect insecure configurations. Enhanced documentation to aid memory diagnostics and introduced sensitive property handling for scripting components. Addressed robustness in data serialization and enforced explicit permissions for custom code execution. Leveraged Java, Groovy, and Spring, applying skills in backend development, dependency management, and unit testing to improve maintainability, security posture, and operational transparency across the codebase.

May 1, 2026For May 2026, the team focused on aligning NiFi Registry with current PostgreSQL versions to enhance testing reliability and performance. The primary deliverable was a PostgreSQL version support update that introduces new test data source factories for Postgres 17 and 18 and retires older versions to streamline compatibility.

Jan 1, 2026January 2026: Delivered two concrete improvements for apache/nifi, focusing on robustness and security. Implemented a bug fix to MapRecord.toMap() to gracefully handle empty arrays, including nested schemas, with regression tests to ensure stability in data processing pipelines. Introduced an explicit permission annotation for Jolt processors to require Execute Code permissions when running custom transformations, strengthening security posture. These changes reduce runtime errors in data processing and enforce tighter authorization for dynamic code execution. Demonstrates Java proficiency, testing discipline, and security-aware design.

Mar 1, 2025March 2025: Delivered a security-focused flow analysis rule for Apache NiFi to detect components that require an SSL Context Service but have it unset, improving TLS usage and reducing misconfiguration risk. The rule targets components like ListenHTTP and HandleHttpRequest and flags them when SSL Context Service is not defined. This work enhances security posture with minimal changes for users.

Feb 1, 2025February 2025 monthly summary for the apache/nifi repo. Key focus: enabling dynamic database connectivity in the ExecuteGroovyScript processor and strengthening test coverage to support attribute-driven DB configurations. Highlights: - Implemented dynamic DB connection resolution for ExecuteGroovyScript via DBCPConnectionLookup, enabling runtime selection of DB connections based on flow attributes. - Updated onInitSQL to pass processor attributes to DBCPService.getConnection, enabling dynamic connection configurations without hard-coded settings. - Added end-to-end test coverage to verify that attributes are correctly propagated to the SQL connection service, improving reliability and regression safety. - This work advances NIFI-5579, improving flexibility, scalability, and maintainability of DB connections in Groovy-scripted flows, with tangible business value for deployment simplicity and runtime adaptability.
