Supercharge Your Percentile Calculations for Big Data (Part I)

Posted by Daren Drummond on Feb 23, 2018

Additional contribution by: Santanu Chatterjee, Trystan Leftwich, Bryan Naden.

 

A new and powerful method of computing percentile estimates on Big Data is now available to you! By combining the well known t-Digest algorithm with AtScale’s semantic layer and smart aggregation features AtScale addresses gaps in both the Business Intelligence and Big Data landscapes. Most BI tools have features to compute and display various percentiles (i.e. medians, interquartile ranges, etc), but they move data for processing which dramatically limits the size of the analysis.  The Hadoop-based SQL engines (Hive, Impala, Spark) can compute approximate percentiles on large datasets, however these expensive calculations are not aggregated and reused to answer similar queries.  AtScale offers robust percentile estimates that work with AtScale’s semantic layer and aggregate tables to provide fast, accurate, and reusable percentile estimates.  

In this three-part blog series we discuss the benefits of percentile estimates and how to compute them in a Big Data environment.  Subscribe today to learn the best practices of percentile estimation on Big Data and more.  Let's dive right in!

It’s Complicated: The Love Hate Relationship with Data.

Posted by Lucio Daza on Feb 12, 2018

Data, Data, Data! All the facts, numbers, and everything in between that, when collected, can be analyzed and decisions made based upon them. Can’t live with it! Can’t live without it!

How to Become Data Driven in Four Easy Steps

Posted by Lucio Daza on Feb 7, 2018

Does your decision-making process need an overhaul? In 2015, over 60% of the decisions made by companies were still based on ‘intuition’ or ‘experience’ of their executive team. With the rise of big data, it is imperative that we make use of such a valuable asset to make fact-based decisions and not just provide an opinion. This means that we need to become data-driven, of course this is easier said than done. It requires more than investing on the latest data and analytics software; it also requires cultural and organizational change.
