TiCDC review
A focused, self-hosted CDC tool for replicating TiDB changes across databases, streams, and storage.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
TiCDC is PingCAP’s open-source, self-hosted change data capture and incremental replication component for TiDB environments. It reads change logs from TiKV, sorts row-level changes, and delivers them through changefeeds to TiDB, MySQL-compatible databases, Kafka, Pulsar, and object storage. Its intended users include teams managing TiDB clusters for disaster recovery, real-time data distribution, analytics pipelines, and heterogeneous database replication.
The product’s strongest area is replication control. TiCDC supports DDL and DML event replication, with filters for tables, databases, DML events, and DDL events. It also supports schema evolution, initial snapshots, and high availability through multiple TiCDC nodes. Downstream options include Amazon S3, Google Cloud Storage, Azure Blob Storage, and NFS alongside database and streaming destinations. Bidirectional TiDB replication further suits environments that need replication between TiDB systems.
TiCDC is a focused choice rather than a broad, managed CDC service. The published product details describe an open-source component managed through CLI and OpenAPI interfaces, with Linux, macOS, and API support. That self-hosted model can fit organizations that want control over TiDB replication infrastructure, but it also places deployment and operational responsibility on the team. Choose TiCDC when TiDB and TiKV are central to the architecture and downstream flexibility matters. Teams seeking a general-purpose CDC tool built around a different source ecosystem should consider a product aligned with that platform instead.
