the &lt;a href=&quot;http://opentracing.io/&quot;&gt;OpenTracing&lt;/a&gt;
community invited me to
+their monthly Google Hangout meetup to give an informal talk on tracing and
+instrumentation in Apache Kudu.&lt;/p&gt;
+
+&lt;p&gt;While Kudu doesn’t currently support distributed tracing using OpenTracing,
+it does have quite a lot of other types of instrumentation, metrics, and
+diagnostics logging. The OpenTracing team was interested to hear about some of
+the approaches that Kudu has used, and so I gave a brief introduction to topics
+including:
+&lt;!--more--&gt;
+- The Kudu &lt;a href=&quot;/docs/administration.html#_diagnostics_logging&quot;&gt;diagnostics
log&lt;/a&gt;
+  which periodically logs metrics and stack traces.
+- The &lt;a href=&quot;/docs/troubleshooting.html#kudu_tracing&quot;&gt;process-wide
tracing&lt;/a&gt;
+  support based on the open source tracing framework implemented by Google Chrome.
+- The &lt;a href=&quot;/docs/troubleshooting.html#kudu_tracing&quot;&gt;stack
watchdog&lt;/a&gt;
+  which helps us find various latency outliers and issues in our libraries and
+  the Linux kernel.
+- &lt;a href=&quot;/docs/troubleshooting.html#heap_sampling&quot;&gt;Heap
sampling&lt;/a&gt; support
+  which helps us understand unexpected memory usage.&lt;/p&gt;
+
+&lt;p&gt;If you’re interested in learning about these topics and more, check out
the video recording
+below. My talk spans the first 34 minutes.&lt;/p&gt;

2.11.&lt;/li&gt;
-          &lt;li&gt;Kudu’s Raft implementation now features pre-elections. In our

-    &lt;p&gt;On November 7th, the Kudu PMC announced that Jordan Birdsell, from State
Farm, had been voted
-in as a new committer and PMC member.&lt;/p&gt;
-
-    &lt;p&gt;Jordan’s contributions include extensive work on the python client,
throwing it some much needed
-love, and bringing it to feature parity with the other clients.&lt;/p&gt;
-
-    &lt;p&gt;Besides his extensive code contributions Jordan has also been active
in reviewing other
-developer’s patches and helping the community in general, on slack and other channels.&lt;/p&gt;
-
-    &lt;p&gt;Jordan has been doing great work and the Kudu PMC was pleased to recognize
his contributions

-    &lt;p&gt;A lot of progress has been done towards the goals that were set in the
scope docs introduced in
-the last couple of posts. Specifically:&lt;/p&gt;
-
-    &lt;ul&gt;
-      &lt;li&gt;
-        &lt;p&gt;Dan Burkert, Todd Lipcon and Alexey Serbin have doubled down on
the security effort. They have
-been working on enabling Kerberos authentication and rpc encryption. The &lt;a href=&quot;https://docs.google.com/document/d/1cPNDTpVkIUo676RlszpTF1gHZ8l0TdbB7zFBAuOuYUw/edit#heading=h.gsibhnd5dyem&quot;&gt;security
scope doc&lt;/a&gt;
-has been updated with the latest plans for security and many patches have been merged already.&lt;/p&gt;
-      &lt;/li&gt;
-      &lt;li&gt;
-        &lt;p&gt;David Alves has continued the work on &lt;a href=&quot;https://s.apache.org/7VCo&quot;&gt;consistency&lt;/a&gt;.
Up for review
-and partially pushed is a patch series to address row history loss if a row is deleted and
then
-re-inserted. Also in progress is work to make sure that scans at a snapshot from followers
-always return same data as if they were executed on the leader. This helps with Read-Your-Writes
-when reading from lagging replicas.&lt;/p&gt;
-      &lt;/li&gt;
-      &lt;li&gt;
-        &lt;p&gt;Adar Dembo has been making good progress &lt;a href=&quot;https://s.apache.org/uOOt&quot;&gt;addressing
issues seen with the LogBlockManager&lt;/a&gt;.
-A series of patches have been merged with various fixes to block managers in general and
to the
-log block manager in particular.&lt;/p&gt;
-      &lt;/li&gt;
-      &lt;li&gt;
-        &lt;p&gt;Dinesh Bhat has been working on improving the manual recovery tools
for Kudu. Namely, he has
-added a tool to force a remote replica copy to a destination server, and a tool to delete
a
-local replica of a tablet. The latter is useful when a tablet cannot come up due to bad state.&lt;/p&gt;
-      &lt;/li&gt;
-      &lt;li&gt;
-        &lt;p&gt;Jean-Daniel Cryans has implemented RPC tracing for the java client,
greatly improving
-debuggability. JD also has added ReplicaSelection to the java client, allowing to perform
-scans on replicas other than the leader, which should be of great help for load-balancing.&lt;/p&gt;
-      &lt;/li&gt;
-      &lt;li&gt;
-        &lt;p&gt;Besides the feature parity contributions, Jordan Birdsell has laid
out a

for Python client work&lt;/a&gt;
-for the 1.2 release. Feedback from other Python client users is certainly appreciated.&lt;/p&gt;
-      &lt;/li&gt;
