当表设置的主键对字段长度进行限定时，canal不识别该列

CREATE TABLE job_execution_script ( app_id INT(11) NOT NULL, job_id INT(11) NOT NULL, script_name VARCHAR(512) NOT NULL DEFAULT '', committer_name VARCHAR(128) NOT NULL DEFAULT '', PRIMARY KEY (app_id,job_id,script_name(100),committer_name) ) ENGINE=INNODB DEFAULT CHARSET=utf8; 当表结构如上时，canal会报 “unknow column script_name(100)” 的ERROR~ 谢谢~
