# `Bandera.Store.TwoLevel`

Default store: an ETS cache in front of a persistent adapter. Whether the cache
is consulted is decided per-call from the runtime `Bandera.Config` snapshot
(read from `:persistent_term`), so caching can be toggled at runtime with no
recompilation. The persistent adapter is also runtime-selected.

## Examples

    iex> alias Bandera.Store.TwoLevel
    iex> TwoLevel.put(:demo, Bandera.Gate.new(:boolean, true))
    iex> {:ok, flag} = TwoLevel.lookup(:demo)
    iex> flag.gates
    [%Bandera.Gate{type: :boolean, for: nil, enabled: true}]
