MySQL uses pt-archiver to archive historical data
Pt-archiver can archive tables to a history database according to specified conditions, and also supports file export, which is very convenient for archiving and cleaning up online historical data.
If you want to archive the data of a table to a table in a historical database, you need to create a table structure in the historical database in advance.
(1) Archive the historical data in the table into the historical data according to the conditions, and generate the archive file locally
