I do a daily "snapshot" restore of my daily backup performed by MariaBackup.
I've just noticed that I see *LOADS* of messages like:
Ignoring data file 'database1/table1.ibd' with space ID 25508, since the redo log references database1/table1.ibd with space ID 25506.
On tables that some jobs perform a "RENAME TABLE", to swap with a new version of them.
I've been seeing this since very long ago, but became more noticeable now that there is a job that does "RENAME TABLE" every 5 minutes.
Is this normal?
Does this mean anything bad to the database or backups? Or to the 'restored' database?
Is there any risk of corruption because of this, or loss of data/tables?
