SummarySupport For Hybrid Partitioned Tables Now Available (19c Preview only)
Hybrid partitioned tables allows a query to access both internal data and multiple data files in the Object Store as single logical table.
Autonomous Database takes advantage of the partitioning information, ensuring that the query only accesses the relevant internal data and/or data files in the Object Store.
