Overview
- Type: Open-source data migration and connector service
- Primary focus: Moving and synchronizing vector and unstructured data between Milvus instances and other systems
- Ecosystem: Built and maintained by Zilliz
- License: Apache-2.0
Features
Based on the available repository information and description, VTS provides:
Core Capabilities
- Transformation and transportation of vector data
- Handling of unstructured data
- Data migration between different Milvus instances
- Connector capabilities to integrate Milvus with external systems
Integration & Connectors
- Designed as a data connector layer around Milvus
- Plugin-oriented structure (via
pluginsdirectory) enabling:- Source and sink plugins for different systems (exact list defined in code/plugins)
- Extensible connectors for additional data sources/targets
Workflow & Orchestration
- Uses a SeaTunnel-based architecture (
seatunnel-api,seatunnel-common,seatunnel-ci-tools), implying:- Pipeline-style configuration for data movement
- Transformation stages between sources and sinks
Deployment & Operations
- Containerized deployment support (via
ci/dockerdirectory) - Kubernetes deployment manifests (under
deploy/kubernetes/seatunnel), enabling:- Clustered or cloud-native deployment
- Integration into existing Kubernetes environments
- Configuration-driven behavior (via
configdirectory) for:- Defining data sources and targets
- Tuning pipeline behavior and runtime parameters
Documentation & Tooling
- Documentation assets (under
docs) including architecture diagrams and usage guidance - Build and runtime utilities (under
bin) to help run and manage VTS components
