What Is Hybrid Columnar Compression?

1.	What Is Hybrid Columnar Compression?
Answer» Hybrid Columnar compression, also CALLED HCC, is a feature of Exadata which is USED for compressing data at column level for a table. It creates compression data units which consist of LOGICAL grouping of columns VALUES typically having several data blocks in it. Each data block has data from columns for multiple rows. This logarithm has the potential to reduce the storage used by the data and reduce DISK I/O enhancing performance for the queries.
