-<h3>Ownership Cache Settings<a class="headerlink" href="#ownership-cache-settings" title="Permalink to this headline">�</a></h3>
-<p>DistributedLog client maintains a ownership cache locally to archieve stable deterministic request routing. Normally,
-the ownership cache is propagated after identified a new owner when performing stream related operations such as write.
-The client also does handshaking when initiating connections to a write proxy or periodically for fast failure detection.
-During handshaking, the client also pull the latest ownership mapping from write proxies to update its local cache, which
-it would help detecting ownership changes quickly, and avoid latency penalty introduced by redirection when ownership changes.</p>
-<ul class="simple">
-<li><em>handshakeWithClientInfo(boolean)</em>: The flag to enable or disable pulling ownership mapping during handshaking.</li>
-<li><em>periodicHandshakeIntervalMs(long)</em>: The periodic handshake interval in milliseconds. Every provided interval, the DL client
-will handshake with existing proxies. It would detect proxy failures during handshaking. If the interval is already greater than
-<cite>periodicOwnershipSyncIntervalMs</cite>, the handshake will pull the latest ownership mapping. Otherwise, it will not. The default
-value is 5 minutes. Setting it to 0 or negative number will disable this feature.</li>
-<li><em>periodicOwnershipSyncIntervalMs(long)</em>: The periodic ownership sync interval, in milliseconds. If periodic handshake is
-enabled, the handshake will sync ownership if the elapsed time is greater than the sync interval.</li>
-<li><em>streamNameRegex(string)</em>: The regex to match the stream names that the client cares about their ownerships.</li>
