def _get_memcache_deadline(self, options=None):
<EOL>return ContextOptions.memcache_deadline(options, self._conn.config)<EOL>
Return the memcache RPC deadline.

        Not to be confused with the memcache timeout, or expiration.

        This is only used by datastore operations when using memcache
        as a cache; it is ignored by the direct memcache calls.

        There is no way to vary this per key or per entity; you must either
        set it on a specific call (e.g. key.get(memcache_deadline=1) or
        in the configuration options of the context's connection.
