<p>A remote log is a replication of a local log.

This means a node can read data that originally came from a node that is offline.</p>

It makes sense to explicitly list what sequence a message is <local hash,
|
|
remote hash, data, seqid> this way I can easily sync a messages prior or
|
|
after a specific number.
|
|
To enable this to be dynamic it might make sense to add page info so
|
|
that I am aware which page I can find seqid on -->

<h2 id="synchronization"><a class="header" href="#synchronization">Synchronization</a></h2>

<h3 id="roles"><a class="header" href="#roles">Roles</a></h3>
|
|
<p>There are four fundamental roles:</p>
|
|
<ol>
|
|
<li>Alice</li>
|
|
<li>Bob</li>
|
|
<li>Name system (NS)</li>
|
|
<li>Content-addressed storage (CAS)</li>
|
|
</ol>
|
|
<p>The <em>remote log</em> protobuf is what is stored in the name system.</p>
|
|
<p>"Bob" can represent anything from 0 to N participants. Unlike Alice,
|
|
Bob only needs read-only access to NS and CAS.</p>

<h3 id="remote-log"><a class="header" href="#remote-log">Remote log</a></h3>
|
|
<p>The remote log lets receiving nodes know what data they are missing. Depending
|
|
on the specific requirements and capabilities of the nodes and name system, the
|
|
information can be referred to differently. We distinguish between three rough
|
|
modes:</p>
|
|
<ol>
|
|
<li>Fully replicated log</li>
|
|
<li>Normal sized page with CAS mapping</li>
|
|
<li>"Linked list" mode - minimally sized page with CAS mapping</li>
|
|
</ol>
|
|
<p><strong>Data format:</strong></p>
|
|
<pre><code class="language-yaml">| H1_3 | H2_3 |
|
|
| H1_2 | H2_2 |
|
|
| H1_1 | H2_1 |
|
|
| ------------|
|
|
| next_page |
|
|
</code></pre>
|
|
<p>Here the upper section indicates a list of ordered pairs, and the lower section
|
|
contains the address for the next page chunk. <code>H1</code> is the native hash function,
|
|
and <code>H2</code> is the one used by the CAS. The numbers corresponds to the messages.</p>
|
|
<p>To indicate which CAS is used, a remote log SHOULD use a multiaddr.</p>
|
|
<p><strong>Embedded data:</strong></p>
|
|
<p>A remote log MAY also choose to embed the wire payloads that corresponds to the
|
|
native hash. This bypasses the need for a dedicated CAS and additional
|
|
round-trips, with a trade-off in bandwidth usage.</p>
|
|
<pre><code class="language-yaml">| H1_3 | | C_3 |
|
|
| H1_2 | | C_2 |
|
|
| H1_1 | | C_1 |
|
|
| -------------|
|
|
| next_page |
|
|
</code></pre>
|
|
<p>Here <code>C</code> stands for the content that would be stored at the CAS.</p>
|
|
<p>Both patterns can be used in parallel, e,g. by storing the last <code>k</code> messages
|
|
directly and use CAS pointers for the rest. Together with the <code>next_page</code> page
|
|
semantics, this gives users flexibility in terms of bandwidth and
|
|
latency/indirection, all the way from a simple linked list to a fully replicated
|
|
log. The latter is useful for things like backups on durable storage.</p>
|
|
<h3 id="next-page-semantics"><a class="header" href="#next-page-semantics">Next page semantics</a></h3>
|
|
<p>The pointer to the 'next page' is another remote log entry, at a previous point
|

in time.</p>
