Methods in org.apache.drill.exec.planner.index with parameters of type IndexCallContext

Modifier and Type	Method	Description
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
static org.apache.calcite.rel.RelCollation	IndexPlanUtils.buildCollationNonCoveringIndexScan(IndexDescriptor indexDesc, org.apache.calcite.rel.type.RelDataType indexScanRowType, org.apache.calcite.rel.type.RelDataType restrictedScanRowType, IndexCallContext context)
static org.apache.calcite.rel.RelCollation	IndexPlanUtils.buildCollationProject(List<org.apache.calcite.rex.RexNode> projectRexs, DrillProjectRelBase project, org.apache.calcite.rel.RelNode input, FunctionalIndexInfo indexInfo, IndexCallContext context)	Build collation property for project, the one closer to the Scan
static ScanPrel	IndexPlanUtils.buildCoveringIndexScan(DrillScanRelBase origScan, IndexGroupScan indexGroupScan, IndexCallContext indexContext, IndexDescriptor indexDesc)
boolean	Statistics.initialize(org.apache.calcite.rex.RexNode condition, DrillScanRelBase scanRel, IndexCallContext context)
static boolean	IndexPlanUtils.isCoveringIndex(IndexCallContext indexContext, FunctionalIndexInfo functionInfo)	For a particular table scan for table T1 and an index on that table, find out if it is a covering index
static org.apache.calcite.rex.RexNode	IndexPlanUtils.rewriteFunctionalRex(IndexCallContext indexContext, DrillParseContext parseContext, DrillProjectRelBase project, org.apache.calcite.rel.RelNode scan, org.apache.calcite.rex.RexNode toRewriteRex, org.apache.calcite.rel.type.RelDataType newRowType, FunctionalIndexInfo functionInfo)	A RexNode forest with three RexNodes for expressions "cast(a.q as int) * 2, b+c, concat(a.q, " world")" on Scan RowType('a', 'b', 'c') will be like this: (0)Call:"*" Call:"concat" / \ / \ (1)Call:CAST 2 Call:"+" (5)Call:ITEM ' world' / \ / \ / \ (2)Call:ITEM TYPE:INT (3)$1 (4)$2 $0 'q' / \ $0 'q' So for above expressions, when visiting the RexNode trees using PathInExpr, we could mark indexed expressions in the trees, as shown in the diagram above are the node (1), then collect the schema paths in the indexed expression but found out of the indexed expression -- node (5), and other regular schema paths (3) (4)
static org.apache.calcite.rel.type.RelDataType	FunctionalIndexHelper.rewriteFunctionalRowType(org.apache.calcite.rel.RelNode origScan, IndexCallContext indexContext, FunctionalIndexInfo functionInfo)
static org.apache.calcite.rel.type.RelDataType	FunctionalIndexHelper.rewriteFunctionalRowType(org.apache.calcite.rel.RelNode origScan, IndexCallContext indexContext, FunctionalIndexInfo functionInfo, Collection<SchemaPath> addedPaths)	if a field in rowType serves only the to-be-replaced column(s), we should replace it with new name "$1", otherwise we should keep this dataTypeField and add a new one for "$1"
static void	IndexPlanUtils.updateSortExpression(IndexCallContext indexContext, List<org.apache.calcite.rel.RelFieldCollation> coll)	generate logical expressions for sort rexNodes in SortRel, the result is store to IndexPlanCallContext
