static final class	QueryPlan.Grouper	Query plan node which applies grouping.
static final class	QueryPlan.GroupSort	Query plan node which sorts rows within a group.
static final class	QueryPlan.Identity	Query plan node which represents a single row with no columns.
static final class	QueryPlan.LoadOne	Query plan node which loads at most one row from a table.
static final class	QueryPlan.Mapper	Query plan node which applies custom row mapping and filtering.
static final class	QueryPlan.MergeConcat	Query plan node which represents a concatenated set of plans which have an explicit ordering, and source rows are compared to each other to maintain the ordering.
static final class	QueryPlan.MergeUnion	Query plan node which represents a union set of plans which have an common ordering, and rows are compared to each other for eliminating duplicates.
static class	QueryPlan.NaturalJoin	Query plan node which joins a target to a source based on a common set of columns.

static final class	QueryPlan.RangeUnion	Query plan node which represents a union set of plans, where each source plan is limited to a range, and all sources produce rows in the same order.
static class	QueryPlan.Scan	Query plan node which scans a table.
static class	QueryPlan.Set	Query plan node which represents a set of plans.
static class	QueryPlan.Sort	Query plan node which sorts the rows.
