一、环境
- tidb06 mysql5.7.32
- tidb05 clickhouse20.8.3.18
二、创建测试库表写入测试数据
tidb06库创建复制账户:
|
1
2
|
GRANT SELECT, REPLICATION SLAVE, REPLICATION CLIENT ON *.* TO 'click_rep'@'172.16.0.246' identified by 'jwts996';flush privileges;Query OK, 0 rows affected, 1 warning (0.00 sec) |
tidb06库创建测试库表test01.tb2并且写入测试数据：

clickhouse库的建表创建方法:
|
1
|
CREATE TABLE tb2 ENGINE = MergeTree PARTITION BY toYYYYMM(create_time) ORDER BY create_time AS SELECT * FROM mysql('172.16.0.247:3306', 'test01', 'tb2', 'click_rep', 'jwts996'); |
提示:clichhouse表中要求必须至少包含一个时间字段
