Hi.
I wanted to know if clickhousrake could achieve real time synchronization of data,For example, when my SQL Server data is being updated or dalETE, can the corresponding data of Clickhouse be updated? In addition, is there any guarantee of breakpoint continuation?

用--targetdb指定数据库名称时，使用大写如--targetdb ABC或是--targetdb "ABC"时，在clickhouse会创建名称了小写的abc数据库，请问怎样才能指定大写名称

I can't get this to work, it claims its not written yet.....

I installed it following your instructions, would be great if you could advise, if it is supposed to work.

thanks
Paul

-- mysql表
CREATE TABLE clickhousetest(
id bigint(20) unsigned NOT NULL AUTO_INCREMENT,
verificatTaskUuid varchar(50) NOT NULL COMMENT 'uuid',
checkDuration int(11) DEFAULT NULL,
PRIMARY KEY (id)
)ENGINE=InnoDB AUTO_INCREMENT=1 DEFAULT charset=utf8mb4;

使用命令
chm --src mysql --src-host 192.168.1.2 --src-port 3306 --src-user root --src-password 12d@s --src-database test --src-table clickhousetest --drop-table true --host 192.168.1.1 --port 9000 --user default --password 22sWd --database test
