:persistent_term adapter for storing rarely-written, frequently-read cached values.

This adapter stores values in Erlang's :persistent_term storage, which provides extremely fast read access at the cost of more expensive writes and deletes. It is best suited for configuration values or other data that changes infrequently.

TTL is not supported — values persist until explicitly deleted.

Example

defmodule MyApp.Cache do
  use Cache,
    adapter: Cache.PersistentTerm,
    name: :my_app_persistent_cache,
    opts: []
end
