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.
