org.elasticsearch.xpack.esql.plan.logical.ParameterizedQuery

All Implemented Interfaces:

NamedWriteable, Writeable, Resolvable

public class ParameterizedQuery
extends LeafPlan

Logical plan node representing a parameterized lookup query source. This replaces EsRelation in the lookup node's logical plan, representing a source that receives input pages (match keys) from the exchange and generates parameterized queries against the lookup index.

Method Details

output

public List<Attribute> output()

Description copied from class: QueryPlan

The ordered list of attributes (i.e. columns) this plan produces when executed. Must be called only on resolved plans, otherwise may throw an exception or return wrong results.

Specified by:

output in class QueryPlan<LogicalPlan>

matchFields

public List<MatchConfig> matchFields()

joinOnConditions

@Nullable
public Expression joinOnConditions()

emptyResult

public boolean emptyResult()

writeTo

public void writeTo(StreamOutput out)
             throws IOException

Throws:

IOException

getWriteableName

public String getWriteableName()

expressionsResolved

public boolean expressionsResolved()

Specified by:

expressionsResolved in class LogicalPlan

info

protected NodeInfo<ParameterizedQuery> info()

Description copied from class: Node

Normally, you want to use one of the static create methods to implement this.

For QueryPlans, it is very important that the properties contain all of the expressions and references relevant to this node, and that all the properties are used in the provided constructor; otherwise query plan transformations like QueryPlan#transformExpressionsOnly(Function) will not have an effect.

Specified by:

info in class Node<LogicalPlan>

hashCode

public int hashCode()

Specified by:

hashCode in class LogicalPlan

equals

public boolean equals(Object obj)

Specified by:

equals in class LogicalPlan
