```

Returns the total number of agent events.

# `delete_before`

```

Deletes events older than the given wall-clock time.

# `events_after`

```elixir
@spec events_after(db(), String.t(), non_neg_integer(), pos_integer()) ::
  {:ok, [MingaAgent.EventLog.EventRecord.t()]} | {:error, term()}
```

Returns all events for a session with id greater than the cursor, ordered by id.

# `insert`

```elixir
@spec insert(db(), MingaAgent.EventLog.EventRecord.t()) ::
  {:ok, pos_integer()} | {:error, term()}
```

Inserts an append-only event record.
