Nested joins in Teradata - forum topic by drmkd17

Can anybody please explain how nested joins work in Teradata???
 
What I know about the other joining strategies is that
 
Merge Join : PI-PI join is on the same AMP. Hence no redistribution
                     PI -Non PI join: Non PI column redistributed temporarily in spool.
                     Non PI - NON PI join: Both are redistributed temporarily in spool.
                     Small Table- Large Table : Samll table duplicated in spool and copied on all AMPS
 
HAsh join: Same aas merge join case 4. but small table copied in the AMP memory.
 
PLease validate and let me know for the Nested join
