title: Simplest way to log all messages from an Azure Event Hub
body: <p>I'm using a service which outputs to an Event Hub.</p>
  
  <p>We want to store that output, to be read once per day by a batch job running on Apache Spark. Basically we figured, just get all messages dumped to blobs.</p>
  
  <p><strong>What's the easiest way to capture messages from an Event Hub to Blob Storage?</strong></p>
  
  <p>Our first thought was a Streaming Analytics job, but it demands to parse the raw message (CSV/JSON/Avro), our current format is none of those.</p>
  
  <hr>
  
  <p><em>Update</em> We solved this problem by changing our message format. I'd still like to know if there's any low-impact way to store messages to blobs. Did EventHub have a solution for this before Streaming Analytics arrived?</p>
