title: Azure Table Storage row Replace() call makes next read slower
body: <p>I have implemented a text message module within my app to send receive messages among users just like a simple email application. I'm using Azure Storage Table as the storage.</p>
  
  <p>When reading the inbox, I'm updating <code>MarkAsRead</code> field for new messages when reading, the next immediate reading from the Storage Table within the same PartitionKey takes long time to read the record and then on wards reading is fast until next update done to the Storage Table.</p>
  
  <p>I have tried out with <code>TableOperation.Replace</code> and <code>TableOperation.Merge</code>, both gave me the same performances.</p>
  
  <p>What is the cause for this issue? </p>
