Thanks for testing.  Out of curiousity I tried to enable TokuDB on my

MariaDB [(none)]> INSTALL PLUGIN tokudb SONAME 'ha_tokudb';
ERROR 2006 (HY000): MySQL server has gone away


Unfortunately the Guix service does not seem to enable any kind of
logging, so I haven't dug further.  Loading other plugins seems to work

I am currently trying this patch on Berlin:

There has been some activity around TokuDB in later versions of MariaDB,
maybe we can enable it again with 10.4.  For now, I think we should just
disable it.
