+                  <li><strong>Time series:</strong> save time series data to a <code>ts_kv</code> table in a DB.</li>
+                  <li><strong>Latest values:</strong> save time series data to a <code>ts_kv_latest</code> table in a DB.</li>
+                  <li><strong>WebSockets:</strong> notify WebSockets subscriptions about time series data updates.</li>
+                </ul>
+                
+                For each <em>action</em>, three <strong>persistence strategies</strong> are available:
+                <ul>
+                  <li><strong>On every message:</strong> perform the action for every message.</li>
+                  <li><strong>Deduplicate:</strong> perform the action only for the first message from a particular originator within a configurable interval.</li>
+                  <li><strong>Skip:</strong> never perform the action.</li>
+                </ul>
+                
+                <strong>Persistence strategies</strong> are configured using <em>persistence settings</em>, which support two modes:
+                <ul>
+                  <li><strong>Basic</strong>
+                    <ul>
+                      <li><strong>On every message:</strong> applies the "On every message" strategy to all actions.</li>
+                      <li><strong>Deduplicate:</strong> applies the "Deduplicate" strategy (with a specified interval) to all actions.</li>
+                      <li><strong>WebSockets only:</strong> applies the "Skip" strategy to Time series and Latest values, and the "On every message" strategy to WebSockets.</li>
+                    </ul>
+                  </li>
+                  <li><strong>Advanced:</strong> configure each action’s strategy independently.</li>

+                
+                By default, the timestamp is taken from <code>metadata.ts</code>. You can enable
+                <em>Use server timestamp</em> to always use the current server time instead. This is particularly
+                useful in sequential processing scenarios where messages may arrive with out-of-order timestamps from
+                multiple sources. Note that the DB layer may ignore older records for attributes and latest values,
+                so enabling <em>Use server timestamp</em> can ensure correct ordering.
+                <br><br>
+                The TTL is taken first from <code>metadata.TTL</code>. If absent, the node configuration’s default
+                TTL is used. If neither is set, the tenant profile default applies.
