FlinkTypeFactory	getTypeFactory()	Returns the type factory.

RelBuilder	transform(UnaryOperator<RelBuilder.Config> transform)	Creates a copy of this RelBuilder, with the same state as this, applying a transform to the config.
RelBuilder	watermark(int rowtimeFieldIndex, org.apache.calcite.rex.RexNode watermarkExpr)	Build watermark assigner relational node.
RelBuilder	windowAggregate(LogicalWindow window, RelBuilder.GroupKey groupKey, List<org.apache.flink.table.runtime.groupwindow.NamedWindowProperty> namedProperties, Iterable<RelBuilder.AggCall> aggCalls)	Build window aggregate for either aggregate or table aggregate.

Field Details

FLINK_REL_BUILDER_CONFIG

public static final RelBuilder.Config FLINK_REL_BUILDER_CONFIG

Method Details

of

public static FlinkRelBuilder of(org.apache.calcite.plan.Context context,
 org.apache.calcite.plan.RelOptCluster cluster,
 org.apache.calcite.plan.RelOptSchema relOptSchema)

of

public static FlinkRelBuilder of(org.apache.calcite.plan.RelOptCluster cluster,
 org.apache.calcite.plan.RelOptSchema relOptSchema)

proto

public static org.apache.calcite.tools.RelBuilderFactory proto(org.apache.calcite.plan.Context context)

pushFunctionScan

public static RelBuilder pushFunctionScan(RelBuilder relBuilder,
 org.apache.calcite.sql.SqlOperator operator,
 int inputCount,
 Iterable<org.apache.calcite.rex.RexNode> operands,
 List<String> aliases)

RelBuilder.functionScan(SqlOperator, int, Iterable) cannot work smoothly with aliases which is why we implement a custom one. The method is static because some RelOptRules don't use FlinkRelBuilder.

expand

public RelBuilder expand(List<List<org.apache.calcite.rex.RexNode>> projects,
 int expandIdIndex)

rank

public RelBuilder rank(org.apache.calcite.util.ImmutableBitSet partitionKey,
 org.apache.calcite.rel.RelCollation orderKey,
 org.apache.flink.table.runtime.operators.rank.RankType rankType,
 org.apache.flink.table.runtime.operators.rank.RankRange rankRange,
 org.apache.calcite.rel.type.RelDataTypeField rankNumberType,
 boolean outputRankNumber)

aggregate

public RelBuilder aggregate(RelBuilder.GroupKey groupKey,
 Iterable<RelBuilder.AggCall> aggCalls)

Build non-window aggregate for either aggregate or table aggregate.

Overrides:

aggregate in class RelBuilder

windowAggregate

public RelBuilder windowAggregate(LogicalWindow window,
 RelBuilder.GroupKey groupKey,
 List<org.apache.flink.table.runtime.groupwindow.NamedWindowProperty> namedProperties,
 Iterable<RelBuilder.AggCall> aggCalls)

Build window aggregate for either aggregate or table aggregate.

watermark

public RelBuilder watermark(int rowtimeFieldIndex,
 org.apache.calcite.rex.RexNode watermarkExpr)

Build watermark assigner relational node.

queryOperation

public RelBuilder queryOperation(org.apache.flink.table.operations.QueryOperation queryOperation)

getTypeFactory

public FlinkTypeFactory getTypeFactory()

Description copied from class: RelBuilder

Returns the type factory.

Overrides:

getTypeFactory in class RelBuilder

transform

public RelBuilder transform(UnaryOperator<RelBuilder.Config> transform)

Description copied from class: RelBuilder

Creates a copy of this RelBuilder, with the same state as this, applying a transform to the config.

Overrides:

transform in class RelBuilder
