Constructor Details

TableScanNode

public TableScanNode(PlanNodeId id,
 TableHandle table,
 List<Symbol> outputs,
 Map<Symbol,ColumnHandle> assignments,
 TupleDomain<ColumnHandle> enforcedConstraint,
 Optional<PlanNodeStatsEstimate> statistics,
 boolean updateTarget,
 Optional<Boolean> useConnectorNodePartitioning)

Method Details

newInstance

@Deprecated
public static TableScanNode newInstance(PlanNodeId id,
 TableHandle table,
 List<Symbol> outputs,
 Map<Symbol,ColumnHandle> assignments,
 boolean updateTarget,
 Optional<Boolean> useConnectorNodePartitioning)

Deprecated.

Use explicit constructor instead. Calling this method when transforming the plan may lead to information loss.

fromJson

public static TableScanNode fromJson(PlanNodeId id,
 TableHandle table,
 List<Symbol> outputs,
 Map<Symbol,ColumnHandle> assignments,
 boolean updateTarget,
 Optional<Boolean> useConnectorNodePartitioning)

getTable

public TableHandle getTable()

getOutputSymbols

public List<Symbol> getOutputSymbols()

Specified by:

getOutputSymbols in class PlanNode

getAssignments

public Map<Symbol,ColumnHandle> getAssignments()

getEnforcedConstraint

public TupleDomain<ColumnHandle> getEnforcedConstraint()

A TupleDomain that represents a predicate that has been successfully pushed into this TableScan node. In other words, predicates that were removed from filters above the TableScan node because the TableScan node can guarantee it.

This field is used to make sure that predicates which were previously pushed down do not get lost in subsequent refinements of the table layout.

getStatistics

public Optional<PlanNodeStatsEstimate> getStatistics()

Statistics if already known.

isUpdateTarget

public boolean isUpdateTarget()

getUseConnectorNodePartitioning

public Optional<Boolean> getUseConnectorNodePartitioning()

isUseConnectorNodePartitioning

public boolean isUseConnectorNodePartitioning()

getSources

public List<PlanNode> getSources()

Specified by:

getSources in class PlanNode

accept

public <R,
C> R accept(PlanVisitor<R,C> visitor,
 C context)

Overrides:

accept in class PlanNode

toString

public String toString()

Overrides:

toString in class Object

replaceChildren

public PlanNode replaceChildren(List<PlanNode> newChildren)

Specified by:

replaceChildren in class PlanNode

withUseConnectorNodePartitioning

public TableScanNode withUseConnectorNodePartitioning(boolean useConnectorNodePartitioning)

withTableHandle

public TableScanNode withTableHandle(TableHandle table)
