Enable a single LightRAG server instance to serve multiple isolated workspaces via HTTP header-based routing. This allows multi-tenant SaaS deployments where each tenant's data is completely isolated. Key features: - Header-based workspace routing (LIGHTRAG-WORKSPACE, X-Workspace-ID fallback) - Process-local pool of LightRAG instances with LRU eviction - FastAPI dependency (get_rag) for workspace resolution per request - Full backward compatibility - existing deployments work unchanged - Strict multi-tenant mode option (LIGHTRAG_ALLOW_DEFAULT_WORKSPACE=false) - Configurable pool size (LIGHTRAG_MAX_WORKSPACES_IN_POOL) - Graceful shutdown with workspace finalization Configuration: - LIGHTRAG_DEFAULT_WORKSPACE: Default workspace (falls back to WORKSPACE) - LIGHTRAG_ALLOW_DEFAULT_WORKSPACE: Require explicit header when false - LIGHTRAG_MAX_WORKSPACES_IN_POOL: Max concurrent workspace instances (default: 50) Files: - New: lightrag/api/workspace_manager.py (core multi-workspace module) - New: tests/test_multi_workspace_server.py (17 unit tests) - New: render.yaml (Render deployment blueprint) - Modified: All route files to use get_rag dependency - Updated: README.md, env.example with documentation 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com> |
