SeaTunnel同步Oracle数据至ClickHouse
-- 在SeaTunnel中,将Oracle数据库的数据同步至ClickHouse的示例配置
-- 源端配置:Oracle数据库
-- 配置Oracle数据源
CREATE TABLE oracle_source (
-- 定义字段和类型
id INT,
name STRING,
price DOUBLE,
ts TIMESTAMP
)
DEFINED BY "org.apache.seatunnel.core.source.oracle.OracleSourceFactory"
OPTIONS (
-- 配置Oracle数据源的连接信息
url = "jdbc:oracle:thin:@//host:port/db",
driver = "oracle.jdbc.driver.OracleDriver",
username = "your_username",
password = "your_password",
query = "SELECT id, name, price, ts FROM your_table"
);
-- 目标端配置:ClickHouse
-- 配置ClickHouse数据源
CREATE TABLE clickhouse_sink (
-- 定义字段和类型与Oracle源表保持一致
id INT,
name STRING,
price DOUBLE,
ts TIMESTAMP
)
DEFINED BY "org.apache.seatunnel.core.sink.clickhouse.ClickHouseSinkFactory"
OPTIONS (
-- 配置ClickHouse的连接信息
host = "your_clickhouse_host",
port = "8123",
database = "your_clickhouse_database",
table = "your_clickhouse_table",
user = "your_clickhouse_user",
password = "your_clickhouse_password"
);
-- 数据同步任务
INSERT INTO clickhouse_sink
SELECT * FROM oracle_source;
这个示例展示了如何使用SeaTunnel定义Oracle数据源和ClickHouse数据目标,并通过一个INSERT语句实现数据同步。这是一个简化的例子,实际使用时需要根据具体的数据库表结构、字段类型和连接信息进行相应的调整。
