Modifier and Type	Class and Description
class	AddExchanges
class	AddLocalExchanges
class	BeginTableWrite
class	CheckSubqueryNodesAreRewritten
class	HashGenerationOptimizer
class	ImplementIntersectAndExceptAsUnion Converts INTERSECT and EXCEPT queries into UNION ALL..GROUP BY...WHERE Eg: SELECT a FROM foo INTERSECT SELECT x FROM bar => SELECT a FROM (SELECT a, COUNT(foo_marker) AS foo_cnt, COUNT(bar_marker) AS bar_cnt FROM ( SELECT a, true as foo_marker, null as bar_marker FROM foo UNION ALL SELECT x, null as foo_marker, true as bar_marker FROM bar ) T1 GROUP BY a) T2 WHERE foo_cnt >= 1 AND bar_cnt >= 1;
class	IndexJoinOptimizer
class	LimitPushDown
class	MetadataDeleteOptimizer Converts delete followed immediately by table scan to a special metadata-only delete node
class	MetadataQueryOptimizer Converts cardinality-insensitive aggregations (max, min, "distinct") over partition keys into simple metadata queries
class	OptimizeMixedDistinctAggregations
class	PredicatePushDown
class	PruneUnreferencedOutputs Removes all computation that does is not referenced transitively from the root of the plan
class	ReplicateSemiJoinInDelete
class	SetFlatteningOptimizer
class	StatsRecordingPlanOptimizer
class	TransformQuantifiedComparisonApplyToLateralJoin
class	UnaliasSymbolReferences Re-maps symbol references that are just aliases of each other (e.g., due to projections like $0 := $1) E.g., Output[$0, $1] -> Project[$0 := $2, $1 := $3 * 100] -> Aggregate[$2, $3 := sum($4)] -> ... gets rewritten as Output[$2, $1] -> Project[$2, $1 := $3 * 100] -> Aggregate[$2, $3 := sum($4)] -> ...
