title: write and read on real time pytables
body: <p>I am not sure if what I am thinking would be possible, I would need the help from someone experienced working with HDF5/PyTables.</p>
  
  <p>The escenario would be like this:</p>
  
  <p>Let's say that we have a process, or a machine or a connexion etc, acquiring data, and storing in a HDF5/PyTable format. I will call it store software.</p>
  
  <p>Would it be possible to have another software, I will call it analysis software, running on time?.</p>
  
  <p>If it helps, the store software and the analysis software would be totally independent, even wrote on different languages.</p>
  
  <p>My doubt is that, if the store program is writing the PyTable, <code>mode='w'</code>, then, at the same time, can the analysis program access in <code>mode='r'</code>, and read some data to perform some basic analysis, averages, etc, etc??. </p>
  
  <p>The basic idea of this is to be able to analyze data stored in a PyTable on real time.</p>
  
  <p>Of course any other proposed solution would be appreciated.</p>
