TiGate pulls change logs from TiDB clusters, and pushes them to downstream systems, including MySQL, TiDB, Kafka, Pulsar, Object Storages(e.g. S3), etc. TiGate is the next generation of TiCDC. We build TiGate mainly to address some drawbacks of TiCDC and move forward.

• Better scalability. E.g. support over 1 million tables.
• More efficiency. Use less machine resource to support large volume.
• Better maintainability. E.g. simpler and human readable code, clear code module, and open to extensions.
• Cloud native architecture. We want to design a new architecture from the ground to support the cloud.
