Classes in org.teiid.query.optimizer.relational.rules that implement OptimizerRule

class	RuleAccessPatternValidation Validates that the access pattern(s) of a source are satisfied.
class	RuleAssignOutputElements This rule is responsible for assigning the output elements to every node in the plan.
class	RuleCalculateCost
class	RuleChooseDependent Finds nodes that can be turned into dependent joins
class	RuleChooseJoinStrategy Marks join as a candidate merge join if conditions are met
class	RuleCleanCriteria Removes phantom and TRUE or FALSE criteria
class	RuleCollapseSource
class	RuleCopyCriteria For each join node this rule will find the set of criteria allowed to influence the join (the join criteria, and inner side criteria on non full outer joins) and builds new criteria based upon the equality relationships found.
class	RuleDecomposeJoin Perform the optimization:
class	RuleImplementJoinStrategy Inserts sort nodes for specific join strategies.
class	RuleMergeCriteria
class	RuleMergeVirtual
class	RulePlaceAccess This rule finds all SOURCE nodes and associates ACCESS patterns, ACCESS nodes, and aliases.
class	RulePlanJoins Determines join orderings based upon dependency and cost information The algorithm works as follows: Stage 1.
class	RulePlanProcedures
class	RulePlanSorts Attempts to minimize the cost of sorting operations across the plan.
class	RulePlanUnions Organizes union branches so that push down is possible.
class	RulePushAggregates
class	RulePushLimit Pushes limit nodes to their lowest points.
class	RulePushNonJoinCriteria Pushes on criteria out of the on clause if possible.
class	RulePushSelectCriteria
class	RuleRaiseAccess
class	RuleRaiseNull Will attempt to raise null nodes to their highest points
class	RuleRemoveOptionalJoins Removes optional join nodes if elements originating from that join are not used in the top level project symbols.
class	RuleValidateWhereAll Validates that the any atomic query being sent to a model where the model requires a criteria actually has a criteria.
