Enumerations

AIProvider

Supported AI providers.

public enum AIProvider
{
    OpenAI,        // OpenAI GPT models
    Anthropic,     // Anthropic Claude models
    Gemini,        // Google Gemini models
    AzureOpenAI,   // Azure OpenAI service
    Custom         // Custom/Ollama/LM Studio/OpenRouter
}

StorageProvider

Supported storage backends for document and vector data persistence.

public enum StorageProvider
{
    InMemory,    // RAM storage (non-persistent, for testing and development)
    Redis,       // High-performance cache and storage
    Qdrant       // Vector database for advanced vector search capabilities
}

Note: SQLite and FileSystem are not available as StorageProvider options. They are only available as ConversationStorageProvider options for conversation history storage.

ConversationStorageProvider

Available storage providers for conversation history.

public enum ConversationStorageProvider
{
    Redis,       // Store conversations in Redis
    SQLite,      // Store conversations in SQLite database
    FileSystem,  // Store conversations in file system
    InMemory     // Store conversations in memory (not persistent)
}

Note: If ConversationStorageProvider is not specified in SmartRagOptions, the system uses the same provider as StorageProvider (excluding Qdrant, which doesn’t support conversation storage).

DatabaseType

Supported database types.

public enum DatabaseType
{
    SQLite,       // SQLite embedded database
    SqlServer,    // Microsoft SQL Server
    MySQL,        // MySQL / MariaDB
    PostgreSQL    // PostgreSQL
}

RetryPolicy

Retry policies for failed requests.

public enum RetryPolicy
{
    None,                // No retries
    FixedDelay,         // Fixed delay between retries
    LinearBackoff,      // Linearly increasing delay
    ExponentialBackoff  // Exponentially increasing delay (recommended)
}

AudioProvider

Supported audio transcription providers.

public enum AudioProvider
{
    Whisper     // Whisper.net (Local transcription - only supported provider)
}

Note: Currently, only Whisper.net is supported for local audio transcription. Google Speech-to-Text configuration exists but is not yet implemented.

QueryStrategy

Strategy for query execution.

public enum QueryStrategy
{
    DatabaseOnly,    // Execute database query only
    DocumentOnly,    // Execute document query only
    Hybrid           // Execute both database and document queries
}
