... If the amount of work needed to execute a query is equally divided among the nodes in a shared-nothing cluster, then there is a danger that the time to complete the query will be approximately equal to time for the slowest compute node to complete its assigned task. A node with degraded performance ...

Temporal Data and The Relational Model
... Recall: A relvar R is in 5NF iff every nontrivial join dependency that is satisfied by R is implied by a candidate key of R. A relvar R is in 6NF iff R satisfies no nontrivial join dependencies at all (in which case R is sometimes said to be irreducible). SSSC and SSSC_SINCE are in 5NF but not 6NF ( ...
