create

public static InnodbFilter create(RelOptCluster cluster,
 RelTraitSet traitSet,
 RelNode input,
 RexNode condition,
 IndexCondition indexCondition,
 com.alibaba.innodb.java.reader.schema.TableDef tableDef,
 @Nullable String forceIndexName)

Creates an InnodbFilter.

computeSelfCost

public @Nullable RelOptCost computeSelfCost(RelOptPlanner planner,
 RelMetadataQuery mq)

Description copied from interface: RelNode

Returns the cost of this plan (not including children). The base implementation throws an error; derived classes should override.

NOTE jvs 29-Mar-2006: Don't call this method directly. Instead, use RelMetadataQuery.getNonCumulativeCost(org.apache.calcite.rel.RelNode), which gives plugins a chance to override the rel's default ideas about cost.

Specified by:

computeSelfCost in interface RelNode

Overrides:

computeSelfCost in class Filter

Parameters:

planner - Planner for cost calculation

mq - Metadata query

Returns:

Cost of this plan (not including children)

copy

public InnodbFilter copy(RelTraitSet traitSet,
 RelNode input,
 RexNode condition)

Specified by:

copy in class Filter

implement

public void implement(InnodbRel.Implementor implementor)

Specified by:

implement in interface InnodbRel

explainTerms

public RelWriter explainTerms(RelWriter pw)

Description copied from class: AbstractRelNode

Describes the inputs and attributes of this relational expression. Each node should call super.explainTerms, then call the RelWriter.input(String, RelNode) and RelWriter.item(String, Object) methods for each input and attribute.

Overrides:

explainTerms in class Filter

Parameters:

pw - Plan writer

Returns:

Plan writer for fluent-explain pattern

getImplicitCollation

public RelCollation getImplicitCollation()

Returns the resulting collation by the primary or secondary indexes after filtering.

Returns:

the implicit collation based on the natural sorting by specific index
