title: WriteStream is not able to write Data in Delta Table
body: <p>I am trying to connect Streaming Json files from the streaming path using the below code</p>
  <pre><code>Schema1= &quot;customerId STRING,orderId STRING,products ARRAY&lt;STRUCT&lt;productId: STRING,quantity: STRING,soldPrice: STRING&gt;&gt;,salesRepId STRING,shippingAddress STRUCT&lt;address: STRING,attention: String,city: STRING,state: STRING,zip: STRING&gt;,submittedAt TIMESTAMP&quot;;
  streamingDF = (spark.readStream.schema(Schema1)\
    .option(&quot;maxFilesPerTrigger&quot;, 1).json(stream_path))
  </code></pre>
  <p>After few transformations in streamingDF  Streaming Dataset and trying to write to a Delta Table using below code</p>
  <pre><code>streamingDF.writeStream.outputMode(&quot;append&quot;)\
    .option(&quot;checkpointLocation&quot;, orders_checkpoint_path)\
    .partitionBy(&quot;submitted_yyyy_mm&quot;)\
    .table(&quot;sachin&quot;)
  </code></pre>
  <p>But those records are not inserted into our delta table and also when I checked the dashboard it shows that numInputRows is 0</p>
