Developed and delivered the TabletExtentChecker server utility for the NationalSecurityAgency/datawave repository, focusing on enhancing data integrity and storage efficiency within Apache Accumulo environments. The tool audits tablet extents and optionally compacts tablets that exceed defined boundaries, supporting range-based scanning and merging of contiguous compaction ranges to optimize I/O during maintenance. Implemented as an executable JAR using Java and Hadoop, the solution integrates seamlessly into existing backend workflows. Comprehensive unit tests were created to validate functionality across diverse tablet configurations, ensuring reliability and maintainability. This work automates detection and handling of tablets needing compaction, reducing manual operational overhead.
