+Sample Deployment using vagrant
+================================
+
+This file explains vagrant deployment.
+
+Prerequesites
+--------------
+1. Vagrant: From https://www.vagrantup.com/downloads.html
+2. vagrant-hostmanager plugin: From https://github.com/devopsgroup-io/vagrant-hostmanager
+
+Steps
+-----
+1. Create a snapshot using ./scripts/snapshot
+2. Run vagrant up from the root directory of the enlistment
+3. Vagrant brings up a zookeepers with machine names: zk1,zk2, .... with IP addresses 192.168.50.11,192.168.50.12,....
+4. Vagrant brings the bookies with machine names: node1,node2, ... with IP addresses 192.168.50.51,192.168.50.52,....
+5. The script will also start writeproxies at distributedlog://$PUBLIC_ZOOKEEPER_ADDRESSES/messaging/distributedlog/mynamespace as the namespace. If you want it to point to a different namespace/port/shard, please update the ./vagrant/bk.sh script. 
+6. If you want to run the client on the host machine, please add these node names and their IP addresses to the /etc/hosts file on the host.

+      <p>To run a DistributedLog ensemble, you'll need a set of Zookeeper
+nodes. There is no constraints on the number of Zookeeper nodes you
+need. One node is enough to run your cluster, but for reliability
+purpose, you should run at least 3 nodes.</p>
+<div class="section" id="version">
+<h2>Version</h2>
+<p>DistributedLog leverages zookeepr <cite>multi</cite> operations for metadata updates.
+So the minimum version of zookeeper is 3.4.*. We recommend to run stable
+zookeeper version <cite>3.4.8</cite>.</p>
+</div>
+<div class="section" id="run-zookeeper-from-distributedlog-source">
+<h2>Run ZooKeeper from distributedlog source</h2>
+<p>Since <cite>zookeeper</cite> is one of the dependency of <cite>distributedlog-service</cite>. You could simply
+run <cite>zookeeper</cite> servers using same set of scripts provided in <cite>distributedlog-service</cite>.
+In the following sections, we will describe how to run zookeeper using the scripts provided
+in <cite>distributedlog-service</cite>.</p>
+<div class="section" id="build">
+<h3>Build</h3>
+<p>First of all, build DistributedLog:</p>
+<figure class="code"><div class="highlight"><table><tr><td class="gutter"><pre class="line-numbers"><span class="line-number">1</span>
+</pre></td><td class="code"><pre><code class="bash"><span class="line"><span></span>$ mvn clean install -DskipTests
+</span></code></pre></td></tr></table></div></figure></div>
+<div class="section" id="configuration">
+<h3>Configuration</h3>
+<p>The configuration file <cite>zookeeper.conf.template</cite> under <cite>distributedlog-service/conf</cite> is a template of
+production configuration to run a zookeeper node. Most of the configuration settings are good for
+production usage. You might need to configure following settings according to your environment and
+hardware platform.</p>
+<div class="section" id="ensemble">
+<h4>Ensemble</h4>
+<p>You need to configure the zookeeper servers form this ensemble as below:</p>
+<pre class="literal-block">
+server.1=127.0.0.1:2710:3710:participant;0.0.0.0:2181
+</pre>
+<p>Please check <a class="reference external" href="http://zookeeper.apache.org/">zookeeper</a> website for more configurations.</p>
+</div>
+<div class="section" id="disks">
+<h4>Disks</h4>
+<p>You need to configure following settings according to the disk layout of your hardware.
+It is recommended to put <cite>dataLogDir</cite> under a separated disk from others for performance.</p>
+<pre class="literal-block">
+# the directory where the snapshot is stored.
+dataDir=/tmp/data/zookeeper
+
+# where txlog  are written
+dataLogDir=/tmp/data/zookeeper/txlog
+</pre>
+</div>
+</div>
+<div class="section" id="run">
+<h3>Run</h3>
+<p>As <cite>zookeeper</cite> is shipped as part of <cite>distributedlog-service</cite>, you could use the <cite>dlog-daemon.sh</cite>
+script to start <cite>zookeeper</cite> as daemon thread.</p>
+<p>Start the zookeeper:</p>
+<figure class="code"><div class="highlight"><table><tr><td class="gutter"><pre class="line-numbers"><span class="line-number">1</span>

+<p>DistributedLog (DL) is a high performance replicated log service.
+It offers durability, replication and strong consistency, which provides a fundamental building block
+for building reliable distributed systems, e.g replicated-state-machines, general pub/sub systems,
+distributed databases, distributed queues and etc.</p>
+<p>DistributedLog maintains sequences of records in categories called <em>Logs</em> (aka <em>Log Streams</em>).
+The processes that write records to a DL log are <em>writers</em>, while the processes that read
+from logs and process the records are <em>readers</em>.</p>

+<h3><a class="toc-backref" href="#id2">Logs</a></h3>
+<p>A <strong>log</strong> is an ordered, immutable sequence of <em>log records</em>.</p>
+<div class="figure align-center">
+<img alt="../images/datamodel.png" src="../images/datamodel.png" />
+<p class="caption">Figure 2. Anatomy of a log stream</p>
+</div>
+<div class="section" id="log-records">
+<h4><a class="toc-backref" href="#id3">Log Records</a></h4>
+<p>Each <strong>log record</strong> is a sequence of bytes.
+<strong>Log records</strong> are written sequentially into a <em>log stream</em>, and will be assigned with
+a unique sequence number <em>called</em> <strong>DLSN</strong> (DistributedLog Sequence Number). Besides <em>DLSN</em>,
+applications could assign its own sequence number while constructing log records. The
+application defined sequence number is called <strong>TransactionID</strong> (<em>txid</em>). Either <em>DLSN</em>
+or <em>TransactionID</em> could be used for positioning readers to start reading from a specific
+<em>log record</em>.</p>
+</div>
+<div class="section" id="log-segments">
+<h4><a class="toc-backref" href="#id4">Log Segments</a></h4>
+<p>A <strong>log</strong> is broken down into <em>segments</em>, which each log segment contains its subset of
+records. <strong>Log segments</strong> are distributed and stored in a log segment store (e.g Apache BookKeeper).
+DistributedLog rolls the log segments based on configured rolling policy - either a configurable
+period of time (e.g. every 2 hours) or a configurable maximum size (e.g. every 128MB).
+So the data of logs will be divided into equal-sized <em>log segments</em> and distributed evenly
+across log segment storage nodes. It allows the log to scale beyond a size that will fit on
+a single server and also spread read traffic among the cluster.</p>
+<p>The data of logs will either be kept forever until application <em>explicitly</em> truncates or be retained
+for a configurable period of time. <strong>Explicit Truncation</strong> is useful for building replicated
+state machines such as distributed databases. They usually require strong controls over when
+the data could be truncated. <strong>Time-based Retention</strong> is useful for real-time analytics. They only
+care about the data within a period of time.</p>
+</div>
+<div class="section" id="namespaces">
+<h4><a class="toc-backref" href="#id5">Namespaces</a></h4>
+<p>The <em>log streams</em> belong to same organization are usually categorized and managed under
+a <strong>namespace</strong>. A DL <strong>namespace</strong> is basically for applications to locate where the
+<em>log streams</em> are. Applications could <em>create</em> and <em>delete</em> streams under a namespace,
+and also be able to <em>truncate</em> a stream to given sequence number (either <em>DLSN</em> or <em>TransactionID</em>).</p>
+</div>
+</div>
+<div class="section" id="writers">
+<h3><a class="toc-backref" href="#id6">Writers</a></h3>
+<p>Writers write data into the logs of their choice. All the records are
+appended into the logs in order. The sequencing is done by the writer,
+which means there is only one active writer for a log at a given time.
+DL guarantees correctness when two writers attempt writing to
+to a same log when network partition happens - via fencing mechanism
+in log segment store.</p>
+<p>The log writers are served and managed in a service tier called <em>Write Proxy</em>.
+The <em>Write Proxy</em> is used for accepting fan-in writes from large number
+of clients. Details on <strong>Fan-in and Fan-out</strong> can be found further into this doc.</p>
+</div>
+<div class="section" id="readers">
+<h3><a class="toc-backref" href="#id7">Readers</a></h3>
+<p>Readers read records from the logs of their choice, starting from a provided
+position. The provided position could be either <em>DLSN</em> or <em>TransactionID</em>.
+The readers will read records in strict order from the logs. Different readers
+could read records starting from different positions in a same log.</p>
+<p>Unlike other pub/sub systems, DistributedLog doesn't record/manage readers' positions.
+It leaves the tracking responsibility to applications, as different applications
+might have different requirements on tracking and coordinating positions. It is hard
+to get it right with a single approach. For example, distributed databases might store
+the reader positions along with SSTables, so they would resume applying transactions
+from the positions stored in SSTables. Tracking reader positions could easily be done
+in application level using various stores (e.g. ZooKeeper, FileSystem, or Key/Value Stores).</p>
+<p>The log records could be cached in a service tier called <em>Read Proxy</em>, to serve
+large number of readers. Details on <strong>Fan-in and Fan-out</strong> can be found further into this doc.</p>
+</div>
+<div class="section" id="fan-in-and-fan-out">
+<h3><a class="toc-backref" href="#id8">Fan-in and Fan-out</a></h3>
+<p>The core of DistributedLog supports single-writer, multiple-readers semantics. The service layer
+built on top of the <em>DistributedLog Core</em> to support large scale of number of writers and readers.
+The service layer includes <strong>Write Proxy</strong> and <strong>Read Proxy</strong>. <strong>Write Proxy</strong> manages
+the writers of logs and fail over them when machines are failed. It allows supporting
+which don't care about the log ownership by aggregating writes from many sources (aka <em>Fan-in</em>).
+<strong>Read Proxy</strong> optimize reader path by caching log records in cases where hundreds or
+thousands of readers are consuming a same log stream.</p>
+</div>
+<div class="section" id="guarantees">
+<h3><a class="toc-backref" href="#id9">Guarantees</a></h3>
+<p>At a high-level, DistributedLog gives the following guarantees:</p>
+<ul class="simple">
+<li>Records written by a writer to a log will be appended in the order they are written. That is, if a record <em>R1</em> is written by same writer as a record <em>R2</em>, <em>R1</em> will have a smaller sequence number than <em>R2</em>.</li>
+<li>Readers will see records in same order they were written to the log.</li>
+<li>All records were persisted on disks before acknowledges, to gurantee durability.</li>
+<li>For a log with replication factor of N, DistributedLog tolerates up to N-1 server failures without losing any records appended to the log.</li>
+</ul>
+<p>More details on these guarantees are given in the design section of this documentation.</p>
