Vertica on Kubernetes

Matt Spilchen, Senior Systems Software Engineer
January 26, 2023

This blog post has been updated from an earlier one to use new features that make deploying on your own system easier. Vertica released the VerticaDB operator in August, 2021, which began Vertica’s integration with Kubernetes. The operator automates many Vertica administrator tasks, such as restarting Vertica if any of the nodes go down, upgrading...

High Availability for a Vertica in Eon Mode Database with Read-Only Mode

Sruthi Anumula, Senior Database Support Engineer
January 9, 2023

When Vertica is deployed in Eon Mode, there are two major requirements for high availability: maintaining quorum and shard coverage. If either of them is lost, the whole cluster goes down. Before going into details, let us understand what quorum and shard coverage mean. Quorum: In Eon Mode, more than half of the primary nodes...

Improving COUNT DISTINCT Performance with Approximate Functions

Bryan Herger, Vertica Big Data Solution Architect at Micro Focus
November 16, 2022

A common analytic use case is to find the number of distinct items in a data set. Vertica performs well at solving COUNT DISTINCT in a few ways. Since Vertica stores all data in columns, it is possible to optimize for COUNT DISTINCT by building a projection that is tuned for this use case. Vertica...

Mark Whalley, Manager, Vertica Education
September 20, 2022

The theme for this year’s International Women’s Day (IWD) was given the name #BreakTheBias to get us to imagine a gender equal world. A world free of bias, stereotypes, and discrimination, a world that is diverse, equitable, and inclusive, where difference is valued and celebrated. Together, we can protect women’s equality. At Micro Focus, as...

Detect Outliers Using Isolation Forest

George Larionov
August 2, 2022

The Isolation Forest (IForest) algorithm is a powerful and scalable algorithm for identifying outliers in your data. It uses a unique approach which focuses directly on characterizing outliers instead of normal data points. Specifically, IForest focuses on the two quantitative properties of outliers: they are few and different. A scalable implementation of the Isolation Forest algorithm is available...

Mark Whalley, Manager, Vertica Education
July 18, 2022

Those of you who read my blog post “Take nothing but memories. Leave nothing but footprints” may recall my passion for using Raspberry Pi computers to capture IoT data from aeroplane transponders and GPS satellites, then feeding that streaming data into Apache Kafka and to integrate it with Vertica and perform near real-time analytics and...

What’s needed for a happy software dev team in data analytics?

Mike Perrow, Senior Product Marketing Writer/Editor
July 6, 2022

For an organization to excel at data analytics, the IT team needs to coordinate a number of different disciplines and personnel with experience in those disciplines. This usually includes data analysts, data engineers, and, increasingly, data scientists. The data engineering discipline is sometimes thought of as the plumbing that, like pipes in a house, delivers...

No need to extract data from your database to do your analytics!

Mark Whalley, Manager, Vertica Education
June 16, 2022

While taking a long-awaited, and, IMHO some well-deserved R&R in the sun, I heard that ping notification coming from my backpack, and not being one who can ignore such things, reached for my iPad. With my OOTO email response already set, I should be able to ignore most incoming messages, texts and otherwise, safe in...
