# `Attesto.RefreshStore.ETS`
[🔗](https://github.com/XukuLLC/attesto/blob/v0.13.0/lib/attesto/refresh_store/ets.ex#L1)

Single-node ETS implementation of `Attesto.RefreshStore`.

Tokens live in an ETS table owned by a `GenServer`. The security-
critical `consume/1` (check-unconsumed-and-mark-consumed) is serialised
through the owning process: routing it as a `GenServer.call/2` makes the
read-modify-write atomic without an ETS compare-and-set dance, which is
the simplest correct primitive for a reference store. `insert/1` and
`revoke_family/1` go through the same process so all mutations are
ordered.

This is a per-node store. A multi-node deployment MUST back
`Attesto.RefreshStore` with a shared store whose `consume/1` is atomic
across nodes (e.g. Postgres `UPDATE ... WHERE consumed = false
RETURNING`), or reuse detection only holds per node.

Start options: `:sweep_interval_ms` (default `60_000`). The sweeper
deletes tokens past their expiry; consumed-but-unexpired tokens are
retained so reuse within the TTL window is still detected.

Clear every entry. Test-facing.
