Data mesh is a hot topic in the data world, generating conversations about the benefits and drawbacks of its decentralized approach. Concerns about an explosion of data silos and inconsistent data quality are justified. But to those who feel a bit like Chicken Little, maybe the sky is not falling. Published at: https://www.eckerson.com/articles/data-mesh-the-sky-is-not-falling

In a modern data stack, data is collected from various sources, such as databases, APIs, and third-party applications. This data is then processed and transformed into a usable format for analysis. However, data quality can suffer at every stage of this process, leading to unreliable insights and flawed decision-making.

One of the biggest challenges of maintaining data quality in a modern data stack is the sheer volume and variety of data. With so much data coming in from different sources, ensuring that all data is accurate, complete, and consistent can be challenging.

Another challenge is data lineage. With data flowing through multiple systems, it can be difficult to track its origin and how it has been transformed over time. This lack of transparency can make it challenging to identify and address issues with data quality.

In other words, data observability enables data leaders and executives to have complete visibility into their data infrastructure, ensuring that data is accurate, complete, and trustworthy. By leveraging data observability, organizations can make informed decisions and take action based on data-driven insights.

So why is data observability critical? Well, as organizations continue to generate and collect more data, it becomes increasingly more work to manage and ensure the quality of that data. Research shows that data quality issues cost organizations an average of $15 million annually.

Data engineering and analytics are critical components of a data-driven organization but have different roles and skill sets. Data engineering focuses on the management and manipulation of data. In contrast, data analytics focuses on the interpretation and visualization of data.

Let's start with data engineering. Data engineering involves collecting, processing, storing, and managing large amounts of data. Data engineers design and build data architectures and infrastructure, create pipelines to move data from source systems to storage and processing systems, and ensure data quality and integrity.

Summary

There has been a lot of discussion about the practical application of data mesh and how to implement it in an organization. Jean-Georges Perrin was tasked with designing a new data platform implementation at PayPal and wound up building a data mesh. In this episode he shares that journey and the combination of technical and organizational challenges that he encountered in the process.

Server-side tracking has quickly become a crucial technology to improve data quality and compliance. Real-time data enrichment in a first-party context is the next step to unlocking its full potential. In his presentation, Thomas will share three real-world customer cases that demonstrate the benefits of data enrichment and why it is so important to enrich in real-time:

Data quality can make or break any data initiative or product. If you aren’t able to collect data that is accurate, or you have data sets that have varying structures, or are filled with typos and other issues caused by human error, then the chances drop drastically that your data models will be accurate, or even helpful. When it comes to healthcare, data quality can be an absolute nightmare. With so many different data sources, high data churn rates, and a lack of standardization in many different healthcare categories, it can seem impossible to make quality healthcare more easily accessible to people when they need it. Ribbon Health seeks to change that by using AI to improve the quality of healthcare data and create a data platform with actionable provider information including insurance coverage, prices, and performance. Today’s guests are Nate Fox, the CTO, Co-Founder, and President of Ribbon Health, and Sunna Jo, a former pediatrician who is now a data scientist at Ribbon Health. Throughout the episode, we talk about why data quality in healthcare is messy, why having context around data is necessary to interpret and utilize it properly, how healthcare providers are improving their services because of platforms like Ribbon Health, how to tackle common data cleaning problems, and much more

Traditional techniques for managing data quality break at scale. Machine learning algorithms can automate aspects of the data quality workload, ensuring that the data the business users consume is reliable. This article profiles three tools and approaches that use ML to automate data quality. Published at: https://www.eckerson.com/articles/three-data-quality-automation-tools-you-should-consider

And don’t forget to thank them for their continued support of this show! Modern data teams are dealing with a lot of complexity in their data pipelines and analytical code. Monitoring data quality, tracing incidents, and testing changes can be daunting and often takes hours to days or even weeks. By the time errors have made their way into production, it’s often too late and damage is done. Datafold built automated regression testing to help data and analytics engineers deal with data quality in their pull requests. Datafold shows how a change in SQL code affects your data, both on a statistical level and down to individual rows and values before it gets merged to production. No more shipping and praying, you can now know exactly what will change in your database! Datafold integrates with all major data warehouses as well as frameworks such as Airflow & dbt and seamlessly plugs into CI workflows. Visit dataengineeringpodcast.com/datafold today to book a demo with Datafold. RudderStack helps you build a customer data platform on your warehouse or data lake. Instead of trapping data in a black box, they enable you to easily collect customer data from the entire stack and build an identity graph on your warehouse, giving you full visibility and control. Their SDKs make event streaming from any app or website easy, and their extensive library of integrations enable you to automatically send data to hundreds of downstream tools.

That’s the spirit behind Upsolver SQLake, a new self-service data pipeline platform that lets you build batch and streaming pipelines without falling into the black hole of DAG-based orchestration. All you do is write a query in SQL to declare your transformation, and SQLake will turn it into a continuous pipeline that scales to petabytes and delivers up to the minute fresh data. SQLake supports a broad set of transformations, including high-cardinality joins, aggregations, upserts and window operations. Output data can be streamed into a data lake for query engines like Presto, Trino or Spark SQL, a data warehouse like Snowflake or Redshift., or any other destination you choose. Pricing for SQLake is simple. You pay $99 per terabyte ingested into your data lake using SQLake, and run unlimited transformation pipelines for free. That way data engineers and data users can process to their heart’s content without worrying about their cloud bill. For data engineering podcast listeners, we’re offering a 30 day trial with unlimited data, so go to dataengineeringpodcast.com/upsolver today and see for yourself how to avoid DAG hell.

Active metadata is not a type of metadata, it’s a way of using metadata to power systems. Active metadata is a critical feature of modern data architectures such as data fabric and data mesh. It makes things work such as data access management, data classification, and data quality management.
