A thin wrapper around :persistent_term for storing terms that are rarely updated and read from many processes on the node.

Keys are prefixed with this module's name so they cannot collide with other :persistent_term users. All operations run in the calling process — there is no server process, so reads are as fast as :persistent_term lookups.

Keep in mind that updating a :persistent_term key triggers a global GC scan on all schedulers; use it for config-like data, not hot counters.

Examples

iex> TermStorage.put(:my_key, %{a: 1})
iex> TermStorage.get(:my_key)
{:ok, %{a: 1}}

iex> TermStorage.get(:never_put)
{:error, :not_found}
