What’s New in Dragline (7.1.0): Live Aggregate Projections

Live Aggregate Projections Video

 

HP Vertica 7.1 introduces live aggregate projections. A live aggregate projection is a projection that contains one or more columns of data that have been aggregated from a table.

If you frequently query data that requires aggregation, you could benefit from using a live aggregate projection. Because data in your live aggregate projection is aggregated at load time, rather than at the time you run a query, you can save time and resources. On subsequent data loads, HP Vertica updates the table and loads the aggregated values into the live aggregate projection. If you query the live aggregate projection any time after that, you’ll not only see the same results you would if you queried the data from the table and then aggregated it, but you’ll also use less resources in the process.

Check out this video to learn more about Live Aggregate Projections. Stay tuned for our next video, ‘Top-K Projections’.

What’s New in Dragline (7.1.0): Installing HP Vertica Pulse

Installing HP Vertica Pulse on Vimeo

HP Vertica 7.1.0 introduces the general availability of HP Vertica Pulse, our add-on sentiment analysis package for HP Vertica. Pulse provides a suite of functions that allow you to analyze and extract the sentiment from text, directly from your HP Vertica database. For example, you can use HP Vertica Pulse to analyze sentiment from Tweets or online product reviews to get a feel for how satisfied your customers are about your products or services.

HP Vertica Pulse automatically discovers attributes included in text and scores them using a built-in system dictionary. You can tune user-dictionaries to detect certain words or phrases, to determine how words are scored, and to filter out attributes that are of no interest to you. Because of this flexibility, you can tune HP Vertica Pulse to work for your specific business needs.

Currently, HP Vertica Pulse allows you to analyze English language text only. You can download HP Vertica Pulse as an add-on package for your Enterprise Edition or as a trial for your Community Edition, from my.vertica.com. Additionally, the Innovations section of the HP Vertica Marketplace offers a beta version of Pulse for Spanish only. Take a look at this video to learn how to install Pulse and stay tuned for our next video, ‘Using Pulse’.
