Importance of Data Observability

Data scientists used to be the company’s nerds, but data scientists or data analysts and their older brothers, business intelligence (BI) analysts, have “shined”.

Today’s data scientists and analysts are heroes and MVPs who can transform their businesses with near-real-time analytics and incredibly accurate predictions that improve decision-making, reduce risk, and increase revenue.

companies have invested millions of dollars in cutting-edge data science platforms equipped with capabilities to support their data scientists and accelerate their transformation into data-driven businesses.

So why are so many data scientists still complaining about weaknesses in their work? And ironically, they’re all about the same thing: data. More specifically, data scientists say they will be found:

• Difficulty in finding the right data sets.

• Unreliable training data to train their machine learning models.

A continuously changing data set both in volume and structure.

• Adrift outcomes and predictions given changing data.

• Inadequate visibility while executing their models, jobs and SQLs.

• Tremendous challenges while maintaining high performance.

Driving Blind

It should come as no surprise that the companies that grew up with data science platforms haven’t invested in tools that allow visibility and control over the data itself.

That’s like buying a sports car that accelerates from zero to 100 mph in four flat seconds … that also doesn’t have a windshield, window, or dashboard. In the automotive equivalent of a black box, you have no idea where you are going or how fast you are going, how fast your engine is turning or if your tires are going to explode.

Companies cannot shoulder all of the blame for driving blind. There just weren’t any good data-tracking tools.

So what is data observability? It’s a 360-degree view of the status, processing, and pipelines of your data. Data observability tools take a variety of performance metrics and analyze them to alert you to predict, prevent, and troubleshoot.

In other words, Data Observability focuses on the visibility, control, and optimization of modern data pipelines created using various data technologies in hybrid data lakes and warehouses.

False Promises

There have been tools in the past that claimed to provide observability for data-intensive applications. Many of these were half-finished extensions to Application Performance Management (APM) platforms, which in some cases have been around for nearly two decades. big, older than the rise of data-intensive applications. In addition, they remain firmly rooted in an application-oriented view of the backend of corporate technology.

As a result, their insight into modern data infrastructure is usually patchy or out of date. When data workers need help finding and validating data quality, troubleshooting why the data pipelines that feed their analysis jobs are slowing down, or pinpointing the causes of your data anomalies. or in the case of deviating schemes, the APM-based observability cannot answer your questions.

There are also one-dimensional point solutions that promise observability of the data. Some only work for one platform, like Hadoop. These are usually primitive and also tie you to a single provider. Others focus on a single task, usually data monitoring.

None of them offer the single crystal visibility, prediction, and automation capabilities that today’s heterogeneous data infrastructures and data teams require. And like the APM-based tools above, they are weak at the data discovery, pipeline management and reliability capabilities that data scientists need to keep their work on track to meet their companies’ business goals.

Automated Data Reliability

For data scientists, data reliability is an important aspect of data observability. Data reliability enables data scientists and other members of a data team to diagnose if and when data reliability may affect the desired business outcomes.

These reliability problems often arise due to the combination of the amounts of unstructured external data that is held in data repositories today. According to Gartner, data drift and other symptoms of poor data quality cost businesses an average of $ 12.9 million a year. This seems like a huge understatement to us.In addition, data, schema, and model deviations can have devastating effects on your machine learning initiatives.

Today, data-driven organizations can act to ensure that data delivers on its promises and gets the expected ROI from their data initiatives by doing the following:

• Establish The Right Data Requirements: It is not enough just to have better data quality. The first step is to establish clear requirements for the required data sets and identify where these data sources are located. Once defined, data scientists can determine what features, files, and tables to include, what types of data to expect, and how to extract and integrate the necessary data. The requirements provide a framework for ensuring that the data team is working with the right sources and getting the right data in the right pipelines.

• Emphasizing Data Orchestration: Compared to five years ago, the business environment looks chaotic. There are more applications, sources, use cases, and users, and the continued functioning of all of these elements can cause some of them to quickly get out of sync. Communication, transaction and delivery between teams must be coordinated with one another with high precision for fast delivery.
• Automation And Systems: For data to be trust worthy and data scientists effective, data observability is an important step in increasing reliability and maintaining an automated set of modern data management functions, including AI-driven data reliability, data discovery, and data optimization functions that ensure the accuracy of the data, reliably and completely over the across the entire flow of data without engineering or data science teams having to do heavy work.

Data observability tools reconcile data across the modern distributed data fabric, preventing and healing problematic issues when it comes to data at rest, data in motion and data for consumption. They trump classic, prior-era data quality tools, which were built for an era of structured data focused on relational databases.
