Difference between findAll, getAll and list in Grails

Question

With Grails there are several ways to do the same thing.

Finds all of domain class instances:

Book.findAll()
Book.getAll()
Book.list()

Answer 1

AFAIK, these are all identical

Book.findAll()
Book.getAll()
Book.list()

These will return the same results

Book.findById(1)
Book.get(1)

but get(id) will use the cache (if enabled), so should be preferred to findById(1)
