Downgrade to previous version of Percona Server, alter the tables, then upgrade back to 8.0.28. It has been well documented and blogged for over a year that TokuDB was deprecated and would be removed.

Hi, I have the same problem, but after downgrading to 8.0.27 the tokudb package isn’t available.

I’m on Centos 7. I tried with `yum install percona-server-tokudb` but yum tried to upgrade percona-server-server to 8.0.29.  
So I tried with the RPM, but seems there are a lot of dependencies not resolved.

I have one only table (a log table).

How can I recover my DB?  
I cannot drop the table and I cannot drop the db…

Thank you for your help
