Teradata 13.10 features Block Level Compression (BLC), which provides the capability to perform compression on whole data blocks at the file system level before the data blocks are actually written to storage. Like any compression features, BLC helps save space and reduce I/O.
This BLC utility is for Teradata users to run against TD 13.10 system to select the list of BLC candidate tables and evaluate BLC impact on space and speed for each specific table in interest, to get information for selecting appropriate tables to apply BLC.
