title: Azure Cosmos DB - incorrect and variable document count
body: <p>I have inserted exactly 1 million documents in an Azure Cosmos DB SQL container using the Bulk Executor. No errors were logged. All documents share the same partition key. The container is provisioned for 3,200 RU/s, unlimited storage capacity and single-region write.</p>
  
  <p>When performing a simple count query:</p>
  
  <pre><code>select value count(1) from c where c.partitionKey = @partitionKey
  </code></pre>
  
  <p>I get varying results varying from 303,000 to 307,000.</p>
  
  <p>This count query works fine for smaller partitions (from 10k up to 250k documents).</p>
  
  <p>What could cause this strange behavior?</p>
