Extract Data Observability Metrics from Snowflake Environment With SQL

You may have just moved your data warehouse to this amazing new solution called Snowflake. This platform is designed to allow data teams to store and use company data easily.

Compared to traditional storage services, Snowflake can work with a wide range of data types and business intelligence integrations. This makes it even easier for teams to work with each other.

However, having the best tools available won’t be very useful if you are faced with broken pipelines. The good news is that there are steps you can take for extracting Snowflake data observability metrics, so you can assess the health of your data.

But before we jump into the metrics, we first need to understand what data observability is.

What Is Data Observability and Why Is It Important?

Data observability is the ability to understand, diagnose, and manage data health by using various IT tools in the data lifecycle. Companies use a reliable data observability platform as it helps them learn and resolve data issues in real-time using telemetry information such as traces, metrics, and logs.

In this case, observability is more than just monitoring as it allows organizations to improve their security. It does this by keeping track of data movement across tools, servers, and applications. It also allows companies to streamline their business data monitoring, so they can properly manage the internal health of their IT infrastructure through output reviews.

Data observability is essential for organizations as it guarantees a reliable and high-quality flow of data throughout their networks. When this happens, it leads to reduced downtime while enhancing both short- and long-term decision-making processes.

The 5 Pillars of Data Observability

The 5 Pillars of Data Observability

Since data observability tools are designed to evaluate specific problems related to data reliability and quality, it needs to have a foundation in order to be effective. Here are the five main pillars of observability that you need to know.

  • Freshness

    Freshness — also known as timeliness — relates to how recent a piece of data is compared to others. In data observability, the freshness of data plays a significant role in its quality since quality eventually goes down over time.

    For instance, details about a customer will eventually become less accurate over the years as that individual may have moved to a different location, changed their email address, or shifted to a new career.

    Freshness is particularly essential when it comes to making business decisions. After all, old information can easily lead to wasted time, money, and effort.

  • Distribution

    Distribution is the term used when referring to the expected range of a specific dataset. The main goal of this pillar is to inform users that their data falls within an accepted range.

    People use data distribution as it provides them with insight if their tables are reliable. They base their findings on what they can expect from the collected data.

  • Volume

    Volume is used when referring to how complete a data table is while providing insights on how effective used data sources have been. Organizations keep track of the consistency of data flow, so they can identify issues in their data pipeline.

    If they notice any discrepancies in the data volume, this often indicates that there are problems when it comes to data intake.

  • Schema

    Schema is used when referring to how organized the company’s data. This can include the tables and fields that are used within a database.

    If a person observes any changes within an organization’s database, it often means there are broken pieces of data to deal with. That’s why it’s important to keep track of who makes the changes to these tables.

    Taking time to understand the health of a data ecosystem is essential in data observability.

  • Lineage

    Lineage is the term referring to the history of a dataset, which is particularly important in data observability. Detailed lineage records provide information on how data was obtained, what changes were made, and where it is headed. In essence, it provides a complete picture of the data landscape of an organization.

    When you can keep track of your data lineage effectively, you can quickly identify problems as they happen and learn what caused them. Not only is this important in data governance and compliance, but it also helps ensure that the information available can be trusted.
