=============================== Release of a new ViTables video ===============================
`Carabos <http://www.carabos.com/>`_ is very happy to announce the second video of the series dedicated to introducing the main features of ViTables to the public. http://www.carabos.com/products/videos/vitables-2-queries `ViTables <http://www.carabos.com/products/vitables>`_ is a GUI for `PyTables <http://www.pytables.org>`_. 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. ..
