Dumpling is a fast, easy-to-use tool written by Go for dumping data from the database(MySQL, TiDB...) to local/cloud(S3, GCP...) in multifarious formats(SQL, CSV...).
Is your feature request related to a problem? Please describe:
When using the mydumper, the SQL will add the LOW_PRIORITY hint automatically.
e.g.
SELECT /*!40001 LOW_PRIORITY SQL_NO_CACHE */ * FROM `test`.`sbtest1`;
But dumpling doesn't support this.
Describe the feature you'd like:
Add an option to add hint LOW_PRIORITY for all the SQLs. This could help to reduce the impact on online txns in tidb v3 or lower version.
