We're excited to announce the release of Dataround Link v0.9.0! This is a significant milestone release that delivers robust data integration capabilities with support for synchronizing multiple data sources.

About Dataround Link

Dataround Link is an open-source data integration tool designed for multi-source heterogeneous data synchronization. It supports seamless integration and synchronization of structured, semi-structured, and unstructured data. Adopting a zero-code visual design philosophy, it eliminates the need for configuration files or programming, allowing users to easily configure and manage complex data synchronization tasks through an intuitive web interface.

Core Features

• Multi-source Heterogeneous Support - Unified support for structured, semi-structured, and unstructured data sources
• Structured Data Support - Traditional relational databases (MySQL, PostgreSQL, Oracle, SQL Server, TiDB, etc.)
• Semi-structured Data Support - Kafka, JSON, and more
• Unstructured Data Support - Images, videos, model files, documents, and other file types
• Zero-Code Visual Interface - No configuration files or programming required, pure visual operations
• Virtual Table Support - Map semi-structured data from Kafka, JSON, etc. to structured data through virtual tables, enabling synchronization with relational databases
• Based on SeaTunnel - Table data synchronization is implemented based on Apache SeaTunnel, providing stable and reliable data transmission capabilities
