Standard Compression Performance Improvements
Internal changes to the DMF data structures improve the performance of standard compression, especially for tables with many columns. (Standard compression is specified by using the WITH COMPRESSION=DATA clause on the MODIFY or the DECLARE GLOBAL TEMPORARY TABLE statement.)
Compression makes rows smaller and is useful in I/O intensive applications, such as data warehousing.
