Quick Start

1. Open the binlog configuration for the source and target clusters

Configure the following information in the fe.conf and be.conf of both the source and target clusters:

enable_feature_binlog=true

2. Deploy Syncer

2.1. Download the latest package from the following link:

https://apache-doris-releases.oss-accelerate.aliyuncs.com/ccr-syncer-2.1.4-x64.tar.xz

2.2. Start and stop Syncer

# Start
cd bin && sh start_syncer.sh --daemon

# Stop
sh stop_syncer.sh

Step 3. Open the Binlog for the synchronized database/table in the source cluster

-- If synchronizing the entire database, execute the following script to enable binlog for all tables in that database
./enable_db_binlog.sh --host $host --port $port --user $user --password $password --db $db

-- If synchronizing a single table, only enable the binlog for that table by executing:
ALTER TABLE your_table_name ENABLE BINLOG SET ("binlog.enable" = "true");

Step 4. Initiate a synchronization job in Syncer

curl -X POST -H "Content-Type: application/json" -d '{
    "name": "ccr_test",
    "src": {
      "host": "localhost",
      "port": "9030",
      "thrift_port": "9020",
      "user": "root",
      "password": "",
      "database": "your_db_name",
      "table": "your_table_name"
    },
    "dest": {
      "host": "localhost",
      "port": "9030",
      "thrift_port": "9020",
      "user": "root",
      "password": "",
      "database": "your_db_name",
      "table": "your_table_name"
    }
}' http://127.0.0.1:9190/create_ccr

Explanation of the parameters for the synchronization job:

name: The name of the CCR synchronization job, must be unique
host, port: Correspond to the host and MySQL (JDBC) port of the cluster Master FE
user, password: The identity used by Syncer to start transactions and pull data
database, table:
If synchronizing at the database level, fill in your_db_name, and leave your_table_name empty
If synchronizing at the table level, fill in both your_db_name and your_table_name
The name used to initiate the synchronization job can only be used once
