Class SearchOptimizationExpression

java.lang.Object

dev.frostlake.metastore.model.SearchOptimizationExpression

public class SearchOptimizationExpression
extends Object

One configured SEARCH OPTIMIZATION expression — a METHOD over a column, as DESCRIBE SEARCH OPTIMIZATION ON <table> reports it.

Frostlake records these and reports them; nothing in the executor consults them, so no lookup structure exists and no query plan changes (see docs/scope.md). The numbers are handed out once and never reused: dropping expression 2 leaves 1, 3, 4 numbered as they were (live-verified).
