When wood dries it shrinks. When it is dried TOO FAST it may split,

It has been my experience that MILLED lumber when dried TOO FAST will
split. When an ENTIRE LOG is dried without milling it WILL split regardless
of how it is dried.

It is all relative. Factors are the size of the log and the exact wood.
Obviously drying a big log intact at the right speed of drying will be a
passtime so unpopular that nobody can be found actually doing it. Note
however that sawing off the end of logs so as to encourage splitting as much
as possible is quite popular.

Anyway your point is irrelevant since this is milled lumber, although likely
twice or thrice the normal thickness. Given the fact that eastern redcedar
shrinks little it should be doable to dry it free of splitting, but it will
take quite a while (which again will be unpopular).
