Benchmarks

Benchmark dataset adapters. Each benchmark implements the Benchmark interface.

Interface

interface Benchmark {
    name: string
    load(config?: BenchmarkConfig): Promise<void>
    getQuestions(filter?: QuestionFilter): UnifiedQuestion[]
    getHaystackSessions(questionId: string): UnifiedSession[]
    getGroundTruth(questionId: string): string
    getQuestionTypes(): QuestionTypeRegistry
}

Adding a Benchmark

1. Create src/benchmarks/mybenchmark/index.ts
2. Implement Benchmark interface
3. Register in src/benchmarks/index.ts
4. Add to BenchmarkName type in src/types/benchmark.ts

Required returns:

• load() - Parse data, populate internal maps
• getQuestions() - Return UnifiedQuestion[] with filtering support
• getHaystackSessions() - Return UnifiedSession[] for a question
• getGroundTruth() - Return expected answer string
• getQuestionTypes() - Return { [id]: { id, alias, description } }
