In Oracle 12C it’s possible to specify during import compressions settings for a table independent from export settings.

It gives more flexibility during importing data.

impdp .. 
TRANSFORM=TABLE_COMPRESSION_CLAUSE:NONE|"<compression type>"

• NONE – compression ignored during import, taken from tablespace settings
• <compression type> – valid compression clause:
  • NOCOMPRESS : Disables table compression.
  • COMPRESS : Enables basic table compression.
  • ROW STORE COMPRESS: Same as COMPRESS.
  • ROW STORE COMPRESS BASIC : Same as COMPRESS.
  • ROW STORE COMPRESS ADVANCED : Enables advanced compression, also known as OLTP compression.
  • COLUMN STORE COMPRESS FOR {QUERY|ARCHIVE} : Hybrid Columnar Compression (HCC) available in Exadata and ZFS storage appliances.
• Can be set in PL/SQL using DBMS_DATAPUMP.METADATA_TRANSFORM

Example

Import data with dedicated compression type

impdp hr/hr DIRECTORY=dpdump_dir DUMPFILE=hr.dmp
TRANSFORM=TABLE_COMPRESSION_CLAUSE:"ROW STORE COMPRESS"

Have a fun 🙂
