# Command module to allow exporting all cache entries as a list.
#
# This command is extremely expensive as it turns the entire cache table into
# a list, and so should be used sparingly. It's provided purely because it's
# the backing implementation of the `dump/3` command.

@doc """
Retrieves all cache entries as a list.
The returned list is a collection of cache entry records, which is a little
more optimized than doing the same via `stream/3`.
This action should only be used in the case of exports and/or debugging, due
to the memory overhead involved, as well as the large concatenations.
