因为主库socket断掉，清理了canal-deployer/conf/example/meta.data文件

Question

在canal-deployer/conf/example/instance.properties配置文件中配置如下：

canal.instance.master.journal.name=mysql-bin.000001
canal.instance.master.position=260675340

启动canal.deployer一段时间后

查看目录canal-deployer/conf/example/meta.data

{"clientDatas":[{"clientIdentity":{"clientId":1001,"destination":"example","filter":""},"cursor":{"identity":{"slaveId":-1,"sourceAddress":{"address":"xxxx","port":3306}},"postion":{"gtid":"","included":false,"journalName":"mysql-bin.000001","position":45019805,"serverId":1,"timestamp":1668737059000}}}],"destination":"example"}

未执行到配置文件中的点位，塞了好多配置文件之前的点位数据。

不是应该只塞配置文件之后点位的数据吗？这样子删除meta.data重启deployer之后，会产生大量配置文件点位之前的数据。求助各位大神，能否rabbitmq里面只加入配置点位之后的数据？
