Two key features of Oracle Exadata Machine

Smart Scan (Exadata Smart Storage):


Offloads query processing to the storage layer, reducing the amount of data sent to the database servers.

Enables operations like filtering, column projection, and join processing to be performed directly on the storage servers, improving query performance significantly.


Hybrid Columnar Compression (HCC):


Provides advanced data compression techniques to reduce storage requirements and improve I/O performance.

Optimized for both OLTP (Online Transaction Processing) and OLAP (Online Analytical Processing) workloads, enabling faster query execution and efficient storage utilization.
