Teradata PT supports loading Large Object (LOB) data into, and extracting LOB data from, Teradata Database tables.

Large Objects are data types that can be Binary Large Objects (BLOBs) or Character Large Objects (CLOBs).

Depending on how the LOB columns are defined in the Teradata PT schema, Teradata PT uses one of the following two methods:

  • Inline
  • Deferred
to load LOB data into, or extract LOB data from, Teradata Database.
Teradata PT supports the inline mode on all platforms.

Teradata PT supports the deferred mode on all platforms, except for the z/OS platform, because data sets are not assigned to the LOB files.
