Vertica 7 Installer Changes for Optimum Performance

HP Vertica 7 introduces a new installer that helps you configure your system for the best possible performance. How does it do this? Well, the new installer checks your systems and lists any changes that you need to make for optimum performance. Not only that, it gives you a direct link to the documentation page that will help you change your system appropriately. Once you change your system configuration, you can rerun the install and know that your system is optimized to run HP Vertica 7.

Inside the Secret World of the Workload Analyzer

When I’m on a flight sitting next to someone, and we’re making polite conversations, often the question comes up “what do you do?” In these situations, I have to assess whether the person works in the IT industry or is otherwise familiar with the lingo. If not, my stock response is “I fix databases”. This usually warrants a polite nod, and then we both go back to sleep. This over-simplified explanation generally suffices, but in truth, it is wholly inadequate. The truth of the matter is that my job is to ensure that databases don’t get broken in the first place; more specifically – an HP Vertica database. But our clients have different, complex goals in mind, they sometimes configure their systems incorrectly for the kind of stuff they’re doing. I’m constantly looking for ways to empower clients to understand problems to look for before they become bigger problems.

Optimizing Big Data Storage in Vertica

With the explosion of data volumes all enterprises are capturing, new technological solutions, such as HP Vertica, offer a solution to non-expert users who need to analyze and monetize their Big Data. If you are a non-expert user, the Database Designer (DBD) module in HP Vertica can help you choose a physical database design that minimizes storage footprint while optimizing the performance of the input query workload. The DBD can recommend good physical designs as quickly as possible using minimal computing resources.

Facebook and Vertica: A Case for MPP Databases

I have just come back from a business trip to China where I visited several large Chinese telecom customers to talk about the recent big Vertica win at Facebook. Two questions these customers had constantly asked me were: What’s the future of MPP databases? Will Hadoop become one database that rules the whole analytic space?

Database Designer in Vertica 7

With the HP Vertica 7, you can use Database Designer with Management Console. As in previous releases, you can still run Database Designer from Admin Tools, but its integration with Management Console offers an additional easy-to-use method for creating a database design.

Can Vertica Climb a Tree?

The answer is YES if it is the right kind of tree. Here “tree” refers to a common data structure that consists of parent-child hierarchical relationship such as an org chart. Traditionally this kind of hierarchical data structure can be modeled and stored in tables but is usually not simple to navigate and use in a relational database (RDBMS). Some other RDBMS (e.g. Oracle) has a built-in CONNECT_BY function that can be used to find the level of a given node and navigate the tree. However if you take a close look at its syntax, you will realize that it is quite complicated and not at all easy to understand or use.

Visualizing Your Query Plan with Management Console 7

You run your newly crafted query and patiently wait for the results to appear on the terminal. You stare at your clock, waiting. 1 minute, 2 minutes, then 5, then 10. Your heart sinks. Why is it taking so long,? The query should be done by now, you tell yourself. You built your projections to optimize the joins, you’re sure there is enough memory to avoid spilling to disk. You start to doubt yourself at this point, so you’ll check to make sure.

Enter the Flex Zone – Under the Hood

With HP Vertica’s latest release (HP Vertica 7 Crane”), we introduced HP Vertica Flex Zone, based on the patent-pending flex tables technology, which dynamically adapt to whatever schema is present in the data. Flex tables offer dramatic usability improvements over regular tables. In this post, we take a look under the hood and show how flex tables are similar to regular Vertica tables, with a little pinch of magic thrown in.

Enter the FlexZone – Let’s talk ETL

In December, HP released version 7 of the HP Vertica analytics platform which includes, among others, a great new feature called HP Vertica Flex Zone (Flex Zone). Flex Zone enables you to quickly and easily load, explore and analyze some forms of semi-structured data. It eliminates the need for coding-intensive schemas to be defined or applied before the data is loaded for exploration.
