- The drainer outputs `kafka` and you need to set the following parameters in the configuration file:

```
[syncer]
db-type = "kafka"

# when db-type is kafka, you can uncomment this to config the down stream kafka, or it will be the same kafka addrs where drainer pull binlog from.

  • pull -> pulls

# [syncer.to]
# kafka-addrs = "127.0.0.1:9092"
# kafka-version = "0.8.2.0"
```

The data which outputs to kafka follows the binlog format sorted by ts and defined by protobuf. Please refer to [driver](https://github.com/pingcap/tidb-tools/tree/master/tidb_binlog/driver) to access the data and sync to the down stream.

- Deploy Kafka and ZooKeeper cluster before deploying TiDB-Binlog. Make sure that Kafka is 0.9 version or later.
