Re: ndb cluster 7.4.12 seems to limit the number of tables/database to 50 when character set is utf8mb4

Table is full is a resource issue. So normally it should always be
possible to get out of it by configuration.

Most commonly you hit it when
you run out of DataMemory. In this case it seems like it is not
the issue.

You can also hit it when you have configured too few tables,
columns and other meta data objects.

There might be a bit more hints if you use show warnings.
You can also use the ndbinfo table ndb$pools table to see
if there is some resource that is exhausted.

I know that utf8mb4 uses more space than utf8, but wasn't aware
that it needed more metadata of any kind. Still increasing the
metadata configurable sizes is very likely going to solve your
issue.

Also look into the ndbinfo table resources if there is any resource
shortage you can see there.
