0 - 2 of 2 tags for value based compression

Are there any plans to introduce a portlet that mimics the behavior of AtanaSoft's CompressTool on Viewpoint? (Maybe even license the IP from AtanaSoft or work with AtanaSoft for them to develop the portlet)

when select inserting from one table to another -- where both have compression on the same column...  what does teradata do?  Does it need to decompress each & every column first -- to get the value and then attempt to insert it into the destination table by check each compressed value there & then storing it?
