# Applicable Scenario for TiCDC

__*Applicable scenario for TiCDC*__

+ Database disaster recovery
+ Data integration

-------------------------------------------------------------
Database disaster recovery: TiDc can be used in disaster recovery scenarios between homogeneous databases to ensure the eventual consistency of primary and standby cluster data in the event of a disaster. Currently, TiDB is only supported as a primary and standby cluster in this scenario.

Data integration: TiCDC provides the TiCDC Canal-JSON Protocol, which supports other systems to subscribe to data changes, and can provide data sources for monitoring, cache, full-text indexing, data analysis, master-slave replication of heterogeneous databases, etc.
