Question 1

How does TiFlow compare to Debezium for change data capture?

Accepted Answer

TiFlow is TiDB-native and optimized for TiDB replication, offering tight integration but limited to TiDB and MySQL ecosystems. Debezium is database-agnostic, supporting multiple sources like PostgreSQL and MongoDB, making it better for multi-vendor environments.

Question 2

Can TiFlow replicate data from Oracle to TiDB?

Accepted Answer

No, TiFlow's DM component only supports MySQL and MariaDB sources for migration to TiDB. For Oracle, you would need to use intermediate tools or convert the data format first.

Question 3

How to set up TiCDC for real-time replication to Kafka?

Accepted Answer

Configure TiCDC by defining replication tasks that capture TiDB changes and stream them to Kafka topics. This involves setting up TiCDC components and ensuring Kafka connectivity, with specifics detailed in the TiCDC documentation.

Question 4

What are the performance overheads of using TiFlow in a distributed TiDB cluster?

Accepted Answer

TiFlow is designed for scalability but adds overhead for change capture and replication. Proper tuning is required to balance latency and throughput, especially in large-scale deployments with high transaction volumes.

Question 5

Is TiFlow good for migrating large MySQL databases with zero downtime?

Accepted Answer

Yes, TiFlow's DM supports full and incremental replication, allowing continuous data sync before cutover. However, success depends on network stability and schema compatibility to minimize disruptions.

Question 6

How to handle schema changes during TiFlow replication?

Accepted Answer

TiFlow provides mechanisms to manage schema changes, but it requires manual configuration or pauses in replication to ensure consistency, which can be complex in active production environments.
