Yellowbrick data warehouse update boosts workload management

Yellowbrick Data has updated its namesake hybrid cloud data warehouse platform with a series of workload management enhancements.

Yellowbrick Data, which is based in Palo Alto, Calif., provides a data warehouse platform that can run on-premises and in multi-cloud deployments. With the Release 5 update, the vendor has added self-healing clusters to improve workload management capabilities.. Resource mapping also gets a boost, as does a rate-limiting feature the company refers to as “penalty boxing.”

Yellowbrick Release 5 was introduced Nov. 16 and is generally available.

There has been a lot of interest in the cloud data warehouse market with the recent IPO of pure cloud data warehouse vendor Snowflake. While interest is in cloud technologies is high, theres still a place for a high-performance data warehouse that can be deployed and managed on-premises and in a private cloud approach.

That is the niche Yellowbrick occupies, along with vendors such as Greenplum and Netezza that pioneered the niche more than a decade ago, according to Doug Henschen, an analyst at Constellation Research.

“I view the sweet spot as meeting the needs of those who want high scalability and performance at a competitive price point,” he said.

Two cables supporting the 900-ton instruments for the telescope above a radio dish 1,000 feet (305 metres) in diameter broke on August 10 and November 6.

Engineers are concerned other cables could also break at any time, making any attempt at repair excessively dangerous.

The telescope is one of the largest in the world and has been a tool for many astronomical discoveries.

The foundation “prioritises the safety of workers, Arecibo Observatory’s staff and visitors, which makes this decision necessary, although unfortunate,” said NSF Director Sethuraman Panchanathan.

“For nearly six decades, the Arecibo Observatory has served as a beacon for breakthrough science and what a partnership with a community can look like.”

Using the hashtag “WhatAreciboMeansToMe”, messages of sadness at the news spread on Twitter from both professional and amateur astronomers who have used the telescope for their work in observing the cosmos for decades.

“More than a telescope, Arecibo is the reason I am even in astronomy,” local astronomer Kevin Ortiz Ceballos wrote
