DataLink is a distributed, extensible data exchange platform for real-time incremental and offline full synchronization between heterogeneous data sources. It uses a Manager-Worker architecture with Zookeeper coordination and was battle-tested at Ucar Group and Luckin Coffee syncing TBs of data daily.
Use cases
- sync data between heterogeneous databases in real time
- replicate mysql binlog changes to other datastores
- run one-off full table migrations between databases
- manage thousands of sync mappings across hundreds of db instances from a web console
- build a self-hosted alternative to canal, otter, or kafka connect for data sync
When to choose
- you need both real-time incremental and batch full sync in one platform
- you want a web-managed, HA cluster with dynamic load balancing for sync tasks
- you operate at large scale (hundreds of instances, thousands of mappings) and need plugin extensibility
When to avoid
- you need a lightweight single-node sync tool or simple cron-based ETL
- you primarily target cloud-managed CDC services or non-Java ecosystems
- you need actively maintained software with recent releases and large community
