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

Modifier and Type	Method and Description
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 Map<LogicalExpression,Integer>	IndexPlanUtils.getProjectExprs(List<org.apache.calcite.rex.RexNode> projectRexs, DrillProjectRelBase project, org.apache.calcite.rel.RelNode input)
static List<org.apache.calcite.rex.RexNode>	IndexPlanUtils.getProjects(DrillProjectRelBase proj)
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 LogicalExpression	RexToExpression.toDrill(DrillParseContext context, DrillProjectRelBase project, org.apache.calcite.rel.RelNode input, org.apache.calcite.rex.RexNode expr)
