I don't think AMS can completely replace HMS, and that wasn't the goal when AMS was designed. HMS can be registered as an external catalog into AMS, and further, AMS can automatically manage/optimize the Iceberg/Paimon tables within this HMS. But this only applies to Iceberg/Paimon tables. AMS doesn't manage other tables within HMS. At the same time, in some scenarios, you can use the internal catalog provided by AMS directly as the metadata store for Iceberg tables. This means you no longer need to use HMS as the metadata store for Iceberg tables. |
