Subj:   Defining NUSI on PI
 
From:   Chennapragada, Somasankaram

NUSI is generally an all amp operation. The NUSI subtables are built locally on all amps. So whenever a NUSI value is mentioned in where condition, the request goes to all amps.

But, when we define NUSI on a PI, why is it a One-amp operation?

     CREATE INDEX (claimid) ON Claim_PPI;

     EXPLAIN SELECT * FROM Claim_PPI WHERE claimid = 260221;

The table is a PPI table.


BR,

Shankar
