Overview

Package trace implements execution operations for querying trace data.

Index

• func Analyze(criteria *tracev1.QueryRequest, metadata []*commonv1.Metadata, ...) (logical.Plan, error)
• func BuildSchema(tr *databasev1.Trace, indexRules []*databasev1.IndexRule) (logical.Schema, error)
• func DistributedAnalyze(criteria *tracev1.QueryRequest, ss []logical.Schema) (logical.Plan, error)
• type Parent

Functions

func Analyze

func Analyze(criteria *tracev1.QueryRequest, metadata []*commonv1.Metadata, ss []logical.Schema,
	ecc []executor.TraceExecutionContext, traceIDTagNames, spanIDTagNames, timestampTagNames []string,
) (logical.Plan, error)

Analyze converts logical expressions to executable operation tree represented by Plan.

func BuildSchema

func BuildSchema(tr *databasev1.Trace, indexRules []*databasev1.IndexRule) (logical.Schema, error)

BuildSchema returns Schema loaded from the metadata repository.

func DistributedAnalyze

func DistributedAnalyze(criteria *tracev1.QueryRequest, ss []logical.Schema) (logical.Plan, error)

DistributedAnalyze converts logical expressions to executable operation tree represented by Plan.

Types

type Parent

type Parent struct {
	UnresolvedInput logical.UnresolvedPlan
	Input           logical.Plan
}

Parent refers to a parent node in the execution tree(plan).
