In December 2024, Srworkspace4 developed RowCounter delete-marker counting features for both the apache/hbase and HubSpot/hbase repositories. They enhanced the RowCounter tool to quantify different delete marker types, introducing a new command-line option and updating the Mapper logic to classify marker types within HBase rows. Their work included comprehensive unit tests to validate the new functionality, improving data visibility and troubleshooting for operators. Using Java, HBase, and MapReduce, Srworkspace4 demonstrated strong cross-repository collaboration and testing discipline. The features laid a foundation for richer analytics on delete operations, supporting better governance and observability in distributed data environments.
