title: How can one get count, with a where condition in DynamoDB
body: <p>Let us say, We have a situation where instead of getting the total count in a table, get the count of records with a particular status.
  We know DynamoDb is schemaless and still has to count each record one by one to get the total count.
  And yet, How can we leverage the above need using dynamoDb queries?</p>
