Subj:   Multi-Value compression of a Sec-Idx and ipact on Multi-Load
 
From:   Gregg, Bill

Have any of U tried to use multi-value compression on a large table where the attribute to be compresses is a secondary index? If yes, what was the performance Hit when multi-loading the table?

(NCR cautions the use of Multi-Load with MV Compression on secondary indices.)

DETAILS

Attribute = Char(10), NOT NULL

Table > 100M Rows

Distinct Values = 6

Attribute is a secondary index on the table


Thanks,

Bill Gregg
