Class VectorizedMetricsPlan

This class provides an abstraction for vectorized computations.

The "vectorization" is referring to collecting UnaryAggregation Expressions of the same UnaryAggregationKind with the same TypeKind of the operand and between the same Tables together into one group (Bag) to be able to apply vectorized arithmetic to each of the Bags).

Syntax

public class VectorizedMetricsPlan

Constructors

VectorizedMetricsPlan(MetricsPlan, IReadOnlyList<Level>, IReadOnlyDictionary<ColumnReference, Bag>)

Declaration

public VectorizedMetricsPlan(MetricsPlan producePlan, IReadOnlyList<Level> levels, IReadOnlyDictionary<ColumnReference, Bag> expressionLookup)

Parameters

Type	Name	Description
MetricsPlan	producePlan
IReadOnlyList<Level>	levels
IReadOnlyDictionary<ColumnReference, Bag>	expressionLookup

Properties

BagLookup

Because each Bag knows about its Expressions, but Expressions don't know about the Bags they are in, this property provides a way to do such lookup in the context of a single VectorizedMetricsPlan.

Declaration

public IReadOnlyDictionary<ColumnReference, Bag> BagLookup { get; }

Property Value

Type	Description
IReadOnlyDictionary<ColumnReference, Bag>

Levels

Each Level corresponds to a unique Aggregation.

Declaration

public IReadOnlyList<Level> Levels { get; }

Property Value

Type	Description
IReadOnlyList<Level>

ProducePlan

Describes the computation before the first Aggregation Table.

In particular, it can contain TableReferences, DataSources, Joins or Externs. It cannot contain any Aggregations.

Declaration

public MetricsPlan ProducePlan { get; }

Property Value

Type	Description
MetricsPlan
