Teradata Vantage includes a set of Customer Data Space (CDS) tools that show data space consumption at the object, database, and system level. The tools report the logical size of your data in its uncompressed form, and eliminate the need for laborious manual space accounting calculations to find object sizes and estimated compression ratios for block-level compressed data.
Customer Data Space tools consist of a set of macros in the SystemFE database, and a new Data Dictionary view, CDSTableSizeV. For more information, see Teradata Vantage™ - SystemFE Macros, B035-1103 and Teradata Vantage™ - Data Dictionary, B035-1092.
