Equivalent avro record data for map type
<p>I have a avro schema as below, I want an example/sample record for the schema.</p>

<p>Schema:</p>

<pre><code>{
   "name" : "root",
   "type" : "record",
   "fields" : [
      {
         "name" : "sub_rec",
         "type" : {
            "type" : "array",
            "items" : {
               "type" : "map",
               "values" : "string"
            }
         }
      }
   ]
}
</code></pre>

<p>I tried like below, but it does not work</p>

<pre><code>{
    "sub_rec" : {[
        "key1" : "val1",
        "key2" : "val2"
    ]}
}
</code></pre>
