VTS (Vector Transfer Service)

VTS is an open-source tool for transforming and transporting vectors and unstructured data, focused on data migration and connectivity for Milvus and external systems.

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 plugins directory) 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/docker directory)
• Kubernetes deployment manifests (under deploy/kubernetes/seatunnel), enabling:
  • Clustered or cloud-native deployment
  • Integration into existing Kubernetes environments
• Configuration-driven behavior (via config directory) 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

Note: For a complete, up-to-date list of specific source/sink plugins and transformations, refer to the plugins and docs directories in the repository.
