MyDataWork POV — Amazon EMR's multi-catalog feature is a genuine leap forward for data professionals juggling multiple table formats. By allowing seamless queries across Iceberg, Delta Lake, Hudi, and Hive without data replication, it simplifies the complexity of managing diverse data ecosystems. This is a strategic enabler for teams developing complex data systems. The ability to query across AWS accounts without duplicating data is a practical win, reducing overhead and fostering a more agile data environment.
