=========================== Announcing PyTables Pro 2.0 ===========================
PyTables Pro is a library for managing hierarchical datasets and designed to efficiently cope with extremely large amounts of data with support for full 64-bit file addressing. PyTables Pro runs on top of the HDF5 library and NumPy package for achieving maximum throughput and convenient use. The main difference between PyTables Pro and regular PyTables is that the Pro version includes OPSI, a new indexing technology, allowing to perform data lookups in tables exceeding 10 gigarows (10**10 rows) in less than 1 tenth of a second. After more than two years of continuous development and about five months of exhaustive testing and benchmarking, we are very happy to announce that PyTables Pro 2.0 (final) is here. Wearing more than 15000 tests and having passed the complete test suite in the most common platforms (Windows, Mac OS X, Linux 32-bit and Linux 64-bit), we are pretty confident that PyTables Pro 2.0 is ready to be used in production scenarios, bringing maximum stability and top performance to those users who need it. For more info about PyTables Pro, see: http://www.carabos.com/products/pytables-pro As already said, PyTables Pro includes, as its most distinguishing feature, the powerful OPSI technology that allows to index very large amounts of data very rapidly while allowing first-class query response times. Its operational details as well as exhaustive benchmarks are explained with full detail in the OPSI white paper: http://www.carabos.com/docs/OPSI-indexes.pdf You can buy PyTables Pro at the Carabos shop: http://www.carabos.com/buy Coinciding with the publication of PyTables Pro we are introducing an innovative liberation process that will allow to ultimate release the PyTables Pro 2.x series as open source. You may want to know that, by buying a PyTables Pro license, you are contributing to this process.
