NineData Data Replication (Doris Documentation)

NineData Data Replication supports offline and real-time data replication between various homogeneous and heterogeneous data sources. It is suitable for various business scenarios such as data migration, database scaling, database version upgrades, disaster recovery, multi-live in different locations, data warehouse and data lake data integration.

For Doris data sources, NineData Data Replication supports the following replication links:

  • Doris ⇋ MySQL

  • Doris ⇋ Oracle

  • Doris ⇋ Doris

  • Doris ⇋ GaussDB

  • Doris ⇋ openGauss

  • Doris ⇋ PostgreSQL

  • Doris ⇋ ClickHouse

  • Doris ⇋ Greenplum

  • Doris ⇋ SelectDB

  • Doris ⇋ StarRocks

  • Doris ⇋ SingleStore

This article takes MySQL replication to Doris as an example to introduce task configuration methods.

Lightweight Deployment Options​

Step Three: Manage Synchronization Tasks​

You can monitor various indicators of synchronization tasks in real-time, and you can also use the built-in data comparison function to automatically compare the data on both ends after synchronization to ensure data consistency.

NineData also supports replication throttling. If the replication task occupies too many read and write resources, you can limit the write rate to ensure the performance of online business.
