Modifier and Type	Method and Description
boolean	AbstractIndexCollection.addIndex(IndexDescriptor index)
boolean	IndexCollection.addIndex(IndexDescriptor index) Add a new index to the collection.
void	IndexSelector.addIndex(IndexDescriptor indexDesc, boolean isCovering, int numProjectedFields)
static org.apache.calcite.rel.RelCollation	IndexPlanUtils.buildCollationCoveringIndexScan(IndexDescriptor indexDesc, IndexCallContext context) Build the collation property for index scan
static org.apache.calcite.rel.RelCollation	IndexPlanUtils.buildCollationForExpressions(Map<LogicalExpression,Integer> projectExprs, IndexDescriptor indexDesc, IndexCallContext context) Given index, compute the collations for a list of projected expressions(from Scan's rowType or Project's ) in the context

DrillTable	IndexDiscoverBase.buildDrillTable(IndexDescriptor idxDesc) Abstract function getDrillTable will be implemented the IndexDiscover within storage plugin(e.g.
String	Statistics.buildUniqueIndexIdentifier(IndexDescriptor idx) Returns a unique index identifier
String	MapRDBStatistics.buildUniqueIndexIdentifier(IndexDescriptor idx)
static IndexPlanUtils.ConditionIndexed	IndexPlanUtils.conditionIndexed(IndexableExprMarker exprMarker, IndexDescriptor indexDesc) Check if any of the fields of the index are present in a list of LogicalExpressions supplied as part of IndexableExprMarker
DrillTable	IndexDiscoverBase.getExternalDrillTable(IndexDescriptor idxDesc) When there is storageName in IndexDescriptor, get a DrillTable instance based on the StorageName and other informaiton in idxDesc that helps identifying the table.
abstract DrillTable	IndexDiscoverBase.getNativeDrillTable(IndexDescriptor idxDesc) When it is native index(index provided by native storage plugin), the actual IndexDiscover should provide the implementation to get the DrillTable object of index, Otherwise, we call IndexDiscoverable interface exposed from external storage plugin's SchemaFactory to get the desired DrillTable.
DrillTable	MapRDBIndexDiscover.getNativeDrillTable(IndexDescriptor idxDescriptor)
boolean	IndexConditionInfo.Builder.isConditionPrefix(IndexDescriptor indexDesc, org.apache.calcite.rex.RexNode initCondition) Given a RexNode corresponding to the condition expression tree and the index descriptor, check if one or more columns involved in the condition tree form a prefix of the columns in the index keys.
