36 * Client daemon which the chunk belongs to can be identified by either
37 * proto (daemon protocol) + instance + VRF.
38 * If the client then passes a non-empty value to keep field when it requests
39 * for chunks, the chunks won't be garbage collected and the client will be
40 * responsible of its release.
41 * Otherwise, if the keep field is not set (value 0) for the chunk, it will be
42 * automatically released when the client disconnects or when it reconnects
43 * (in case it died unexpectedly, we can know it's the same because it will have
44 * the same proto and instance values)
