-        <p>Today’s data is dynamic and application-driven. The growth of a new era of business applications driven by industry trends such as web, social, mobile, and Internet of Things are generating datasets with new data types and new data models. These applications are iterative, and the associated data models typically are semi-structured, schema-less and constantly evolving. Semi-structured data models can be complex/nested, schema-less, and capable of having varying fields in every single row and of constantly evolving as fields get added and removed frequently to meet business requirements. </p>
-
-<p>This tutorial shows you how to natively query dynamic datasets, such as JSON, and derive insights from any type of data in minutes. The dataset used in the example is from the Yelp check-ins dataset, which has the following structure:</p>
-<div class="highlight"><pre><code class="language-text" data-lang="text">check-in
-{
-    &#39;type&#39;: &#39;checkin&#39;,
-    &#39;business_id&#39;: (encrypted business id),
-    &#39;checkin_info&#39;: {
-        &#39;0-0&#39;: (number of checkins from 00:00 to 01:00 on all Sundays),
-        &#39;1-0&#39;: (number of checkins from 01:00 to 02:00 on all Sundays),
-        ...
-        &#39;14-4&#39;: (number of checkins from 14:00 to 15:00 on all Thursdays),
-        ...
-        &#39;23-6&#39;: (number of checkins from 23:00 to 00:00 on all Saturdays)
-    }, # if there was no checkin for a hour-day block it will not be in the dataset
-}
-</code></pre></div>
-<p>It is worth repeating the comment at the bottom of this snippet:</p>
-<div class="highlight"><pre><code class="language-text" data-lang="text"> # if there was no checkin for a hour-day block it will not be in the dataset. 
-</code></pre></div>
-<p>The element names that you see in the <code>checkin_info</code> are unknown upfront and can vary for every row. The data, although simple, is highly dynamic data. To analyze the data there is no need to first represent this dataset in a flattened relational structure, as you would using any other SQL on Hadoop technology.</p>
-
-<hr>
-
-<p>Step 1: First download Drill, if you have not yet done so, onto your machine</p>
-<div class="highlight"><pre><code class="language-text" data-lang="text">http://drill.apache.org/download/
-tar -xvf apache-drill-0.9.0.tar
-</code></pre></div>
-<p>Install Drill locally on your desktop (embedded mode). You don’t need Hadoop.</p>
-
-<hr>
-
-<p>Step 2: Start the Drill shell.</p>
-<div class="highlight"><pre><code class="language-text" data-lang="text">bin/drill-embedded
-</code></pre></div>
-<hr>
-
-<p>Step 3: Start analyzing the data using SQL</p>
-
-<p>First, let’s take a look at the dataset:</p>

-
-<p>You query the data in JSON files directly. Schema definitions in Hive store are not necessary. The names of the elements within the <code>checkin_info</code> column are different between the first and second row.</p>
-
-<p>Drill provides a function called KVGEN (Key Value Generator) which is useful when working with complex data that contains arbitrary maps consisting of dynamic and unknown element names such as checkin_info. KVGEN turns the dynamic map into an array of key-value pairs where keys represent the dynamic element names.</p>
-
-<p>Let’s apply KVGEN on the <code>checkin_info</code> element to generate key-value pairs.</p>

-<p>You can get value from the data quickly by applying both KVGEN and FLATTEN functions on the datasets on the fly--no need for time-consuming schema definitions and data storage in intermediate formats.</p>
-
-<p>On the output of flattened data, you use standard SQL functionality such as filters , aggregates, and sort. Let’s see a few examples.</p>
