PROFILE
Kodey Converse
Kodey contributed to the HubSpot/hbase repository by developing and refining backup and recovery features for distributed HBase systems. Over three months, Kodey implemented a system table restore procedure using Java and Protobuf, introducing a disable-restore-enable flow with snapshot-based recovery and comprehensive end-to-end testing. Kodey also enhanced incremental backup correctness by preserving HFile sequence IDs, updating HFileOutputFormat2, and ensuring client compatibility through targeted tests. Addressing operational efficiency, Kodey fixed WAL backup duplication for decommissioned hosts, reducing storage costs and improving backup reliability. The work demonstrated depth in backend development, distributed systems, and unit testing, with a focus on robust, maintainable solutions.
