Note: Performance may vary based on hardware, model selection, and document complexity
Scalability Analysis
The benchmark results demonstrate GoRAG's exceptional scalability:
-
Small-Scale Scalability:
- When indexing 10 documents, the average time per document decreases slightly (from 48.1ms to 45.9ms), indicating efficient batch processing.
- Query performance remains nearly identical when searching across 10 documents compared to a single document.
-
Large-Scale Scalability:
- Successfully indexes 100 documents (100,000+ characters) in just 7.6 seconds
- Maintains query performance even with 100 documents, only increasing by ~40% compared to single-document queries
- Average indexing time per document remains efficient at ~76ms even at scale
-
Bible-Scale Scalability:
- Successfully indexes 10,100 documents (1.6M+ characters) in just 206 seconds
- Maintains query performance even with 10,100 documents, only increasing by ~200% compared to single-document queries
- Average indexing time per document improves to ~20.4ms at Bible-scale, demonstrating excellent batch processing efficiency
- Query performance scales logarithmically, showing that GoRAG can handle large document collections without significant performance degradation
-
Multi-language Support:
- All tests used mixed English and Chinese content
- No performance degradation observed with multilingual documents
-
Production Readiness:
- The Bible-scale benchmark results confirm that GoRAG is capable of handling enterprise-level document volumes
- The performance remains consistent even as the document collection grows by two orders of magnitude
- The logarithmic scaling of query performance indicates that GoRAG can handle even larger document collections
-
Mixed-Format Support:
- Successfully processes mixed-format document collections (HTML and text files)
- Automatically selects the appropriate parser based on file type
- Demonstrates the flexibility to handle real-world document collections with diverse formats
These results validate that GoRAG is designed for production use cases with substantial document collections, making it an ideal choice for enterprise applications requiring high-performance RAG capabilities. The Bible-scale benchmark demonstrates that GoRAG can handle the type of large document collections typically found in enterprise environments, such as entire codebases, documentation libraries, or knowledge bases. The mixed-format benchmark further confirms its ability to process real-world document collections with diverse formats.

rag.WithParser(textParser), // Set text parser as default
rag.WithVectorStore(memory.NewStore()),
rag.WithEmbedder(embedderInstance),
rag.WithLLM(llmInstance),
)
// Add HTML parser for HTML files
engine.AddParser("html", htmlParser)
if err != nil {
log.Fatal(err)
}
// Index documents
err = engine.Index(ctx, rag.Source{
Type: "text",
Content: "Go is an open source programming language...",
})
// Query with custom prompt template
resp, err := engine.Query(ctx, "What is Go?", rag.QueryOptions{
TopK: 5,
PromptTemplate: "You are a helpful assistant. Based on the following context:\n\n{context}\n\nAnswer the question: {question}",
})
log.Println(resp.Answer)
}
โก Concurrent Directory Indexing (Unique Feature!)
GoRAG provides built-in concurrent directory indexing - a feature not available in other RAG frameworks!
package main
import (
"context"
"log"
"os"
embedder "github.com/DotNetAge/gorag/embedding/openai"
llm "github.com/DotNetAge/gorag/llm/openai"
"github.com/DotNetAge/gorag/rag"
"github.com/DotNetAge/gorag/vectorstore/memory"
)
func main() {
ctx := context.Background()
apiKey := os.Getenv("OPENAI_API_KEY")
// Create RAG engine - parsers are auto-loaded!
embedderInstance, _ := embedder.New(embedder.Config{APIKey: apiKey})
llmInstance, _ := llm.New(llm.Config{APIKey: apiKey})
engine, err := rag.New(
rag.WithVectorStore(memory.NewStore()),
rag.WithEmbedder(embedderInstance),
rag.WithLLM(llmInstance),
)
if err != nil {
log.Fatal(err)
}
// ๐ Index entire directory with 10 concurrent workers!
// Automatically detects file types and selects appropriate parsers
err = engine.IndexDirectory(ctx, "./documents")
if err != nil {
log.Fatal(err)
}
// Or use async indexing for background processing
err = engine.AsyncIndexDirectory(ctx, "./large-document-collection")
if err != nil {
log.Fatal(err)
}
// Query as usual
resp, err := engine.Query(ctx, "What information is in my documents?", rag.QueryOptions{
TopK: 5,
})
log.Println(resp.Answer)
}
Key Benefits:
- โ
10 concurrent workers - Process multiple files simultaneously
- โ
Automatic parser selection - Detects file types by extension (.pdf, .docx, .html, etc.)
- โ
Streaming large files - Handles 100M+ files without memory issues
- โ
Error aggregation - Collects all errors and returns them at once
- โ
Context cancellation - Respects context cancellation for graceful shutdown
๐ Advanced RAG Patterns
Multi-hop RAG for Complex Questions
Use multi-hop RAG to handle complex questions that require information from multiple documents:
package main
import (
"context"
"log"
"os"
embedder "github.com/DotNetAge/gorag/embedding/openai"
llm "github.com/DotNetAge/gorag/llm/openai"
"github.com/DotNetAge/gorag/rag"
"github.com/DotNetAge/gorag/vectorstore/memory"
)
func main() {
ctx := context.Background()
apiKey := os.Getenv("OPENAI_API_KEY")
// Create RAG engine
embedderInstance, _ := embedder.New(embedder.Config{APIKey: apiKey})
llmInstance, _ := llm.New(llm.Config{APIKey: apiKey})
engine, err := rag.New(
rag.WithVectorStore(memory.NewStore()),
rag.WithEmbedder(embedderInstance),
rag.WithLLM(llmInstance),
)
if err != nil {
log.Fatal(err)
}
// Index documents about different companies
err = engine.Index(ctx, rag.Source{
Type: "text",
Content: "Apple is investing heavily in AI research and development. They have launched several AI features in iOS 18 including Apple Intelligence.",
})
err = engine.Index(ctx, rag.Source{
Type: "text",
Content: "Microsoft has made significant AI investments through OpenAI and has integrated AI features across its product lineup including Office 365 and Azure.",
})
// Use multi-hop RAG for complex comparison question
resp, err := engine.Query(ctx, "Compare Apple and Microsoft's AI investments", rag.QueryOptions{
UseMultiHopRAG: true,
MaxHops: 3, // Maximum number of retrieval hops
})
log.Println("Answer:", resp.Answer)
log.Println("Sources:", len(resp.Sources), "documents used")
}
Agentic RAG for Autonomous Retrieval
Use agentic RAG for autonomous retrieval with intelligent decision-making:
package main
import (
"context"
"log"
"os"
embedder "github.com/DotNetAge/gorag/embedding/openai"
llm "github.com/DotNetAge/gorag/llm/openai"
"github.com/DotNetAge/gorag/rag"
"github.com/DotNetAge/gorag/vectorstore/memory"
)
func main() {
ctx := context.Background()
apiKey := os.Getenv("OPENAI_API_KEY")
// Create RAG engine
embedderInstance, _ := embedder.New(embedder.Config{APIKey: apiKey})
llmInstance, _ := llm.New(llm.Config{APIKey: apiKey})
engine, err := rag.New(
rag.WithVectorStore(memory.NewStore()),
rag.WithEmbedder(embedderInstance),
rag.WithLLM(llmInstance),
)
if err != nil {
log.Fatal(err)
}
// Index various documents about AI trends
err = engine.Index(ctx, rag.Source{
Type: "text",
Content: "AI trends in 2024 include generative AI, multimodal models, and AI ethics.",
})
err = engine.Index(ctx, rag.Source{
Type: "text",
Content: "Generative AI is being applied across industries including healthcare, finance, and education.",
})
err = engine.Index(ctx, rag.Source{
Type: "text",
Content: "Multimodal AI models can process text, images, and audio simultaneously.",
})
// Use agentic RAG for comprehensive research task
resp, err := engine.Query(ctx, "Write a report on AI trends in 2024", rag.QueryOptions{
UseAgenticRAG: true,
AgentInstructions: "Please generate a comprehensive report on AI trends in 2024, including key technologies, applications, and future outlook.",
})
log.Println("Report:", resp.Answer)
log.Println("Sources:", len(resp.Sources), "documents used")
}
Key Benefits of Advanced RAG:
- โ
Multi-hop RAG - Breaks down complex questions into multiple retrieval steps
- โ
Agentic RAG - Autonomously decides what information to retrieve and when

Examples
- Basic - Simple RAG usage example
- Advanced - Advanced features including streaming and hybrid retrieval
- Web - HTTP API server example
Testing
GoRAG has comprehensive test coverage with both unit tests and integration tests:
Test Coverage
- Overall Coverage: 85%+ across all modules
- Unit Tests: All core modules have comprehensive unit tests
- Integration Tests: Real-world testing with actual vector databases using Testcontainers
- Performance Benchmarks: Built-in benchmarks for Index and Query operations
Running Tests
# Run all unit tests
go test ./...
# Run integration tests (requires Docker)
go test -v ./integration_test/...
# Run tests with coverage
go test -cover ./...
# Run benchmarks
go test -bench=. ./rag/
Integration Testing
Integration tests use Testcontainers to spin up real instances of:
- Milvus - Vector database for production workloads
- Qdrant - High-performance vector search engine
- Weaviate - Semantic search engine with GraphQL API
This ensures that GoRAG works correctly with actual vector databases in production environments.
