Implementation:Infiniflow Ragflow Api Constants

Overview

Concrete registry of API-wide constants for naming limits, service configuration, and resource constraints used across the RAGFlow API layer.

Description

The api.constants module defines shared constant values used throughout the API layer including name length limits, base64 image prefixes, API versioning, request timeout boundaries, and resource size constraints for datasets, files, and memory.

Usage

Import these constants when implementing API endpoints or service methods that need to enforce naming limits, validate file sizes, or reference the API version string.

Inputs

Name	Type	Required	Description
—	—	—	Module-level constants; no inputs

Outputs

Name	Type	Description
NAME_LENGTH_LIMIT	int	Maximum length for entity names (1024)
DATASET_NAME_LIMIT	int	Maximum dataset name length (128)
FILE_NAME_LEN_LIMIT	int	Maximum file name length (255)

Usage Examples

from api.constants import DATASET_NAME_LIMIT, FILE_NAME_LEN_LIMIT

def validate_dataset_name(name: str) -> bool:
    if len(name) > DATASET_NAME_LIMIT:
        raise ValueError(f"Dataset name exceeds {DATASET_NAME_LIMIT} characters")
    return True
