为提高效率，请提供以下信息，问题描述清晰能够更快得到解决：
【TiDB 版本】
v4.0.9
【问题描述】
使用如下语句
"./dumpling -u qdtech -P 4000 -h 127.0.0.1 --filetype sql --threads 1 -o /mnt/tidb-data/20210502/databases -r 10000 -F 256MiB -pWRnYAc8mL3uE04Hf90x5 -T databases --snapshot “2021-05-02 08:00:00” --tidb-mem-quota-query 4294967296 & "
导出了1.9T的SQL，导出成功无报错，导出的TiDB数据库版本为v4.0.9，导入的新的TiDB集群产生的报错，新的TiDB集群为云厂商的TiDB集群，只提供TiDB的IP、端口、用户名、密码，版本为：v4.0.8-dirty
报错信息如下：

恢复的命令如下：

nohup ./tidb-lightning -config tidb-lightning.toml > nohup.out &
编辑成为一个shell脚本，使用shell脚本恢复
备份出来了四个数据库，一个500MB，一个300MB，数据量小的已经恢复到新的TIDB集群，但是这个大的数据库一直卡在370G左右的时候报错。
恢复这个大的数据库的时候有些建表语句出现报错：
ERROR 1101 (42000): BLOB/TEXT/JSON column ‘suy_config’ can’t have a default value
ERROR 1067 (42000): Invalid default value for ‘uptime’
我都已经按照提示，去掉默认值，以及将默认的时间改为”1970-1-1“，改掉之后的建表语句成功执行无报错。
这里报错的表也不是修改建表语句后建的表。
这里的备份、恢复服务器的配置为4核8G内存3T存储的VM。
