Release of a new ViTables video

`Carabos <>`_ is very happy to announce the
second video of the series dedicated to introducing the main features
of ViTables to the public.

`ViTables <>`_  is a GUI for `PyTables
<>`_. It allows to open arbitrarely large PyTables and
HDF5 files and browse their data and metadata in a variety of ways.

This second video explains in depth how to quickly query multi-billion row
tables using ViTables in combination with OPSI [1]_, the powerful indexing
engine that comes with  PyTablesPro. The covered topics are:

 * how to do queries involving several fields a.k.a complex queries
 * how to include the indexes of the selected rows in a query result
 * detailed description of the queries dialog
 * how indexing fields with OPSI affects the speed of queries

It has a running length of about 8 minutes, so you can watch it during any
short break.

We would like to hear your opinion on the video so we can do it better
the next time. We are also open to suggestions for the topics of
future videos.
