title: Apache ignite json field
body: <p>Perhaps I am missing this in the documentation, but is it possible to store and query against json data in Apache Ignite? For example, let's say I have a "table" called "cars" with the following fields:</p>
  
  <pre><code>model
  blueprint
  </code></pre>
  
  <p>The "blueprint" field is actually a json field that may contain data such as:</p>
  
  <pre><code>{
      horsepower: 200,
      mpg: 30
  }
  </code></pre>
  
  <p>Those are not the only fields for the "blueprint" field, and it may contain many more or less fields. Is it possible to run a query such as:</p>
  
  <pre><code>SELECT model FROM cars WHERE blueprint.horsepower &lt; 300 AND blueprint.mpg &gt; 20
  </code></pre>
  
  <p>It is not known in advance what the fields will be for the "blueprint" field, and creating indexes for them is not optional.</p>
  
  <p>Note: This is not a conversation about if this is the logically optimal way to store this information, or how the "blueprint" field should be stored in a separate table. This question is meant to understand if querying against a json field is trivially possible in apache ignite.</p>
