How Observability in Lakeflow Helps You Build Reliable Data Pipelines

As data volume grows, so do the risks for your data platform: from stale pipelines to hidden errors and runaway costs. Without observability integrated into your data engineering solution, you are flying blind and risking impacting not just the health and freshness of your data pipelines, but also missing serious issues in your downstream data, analytics, and AI workloads. With Lakeflow, Databricks' unified and intelligent data engineering solution, you can easily tackle this challenge with built-in observability solutions in an intuitive interface directly within your ETL platform, on top of your Data Intelligence.

In this blog, we will introduce Lakeflow's observability capabilities and show how to build reliable, fresh, and healthy data pipelines.

Observability is Essential for Data Engineering

Observability for data engineering is the ability to discover, monitor, and troubleshoot systems to ensure the ETL operates correctly and effectively. It is the key to maintaining healthy and reliable data pipelines, surfacing insights, and delivering trustworthy downstream analytics.

As organizations manage an increasingly growing number of business-critical pipelines, monitoring and ensuring the reliability of a data platform has become vital for a business. To tackle this challenge, more data engineers are recognizing and seeking the benefits of observability. According to Gartner, 65% of data and analytics leaders expect data observability to become a core part of their data strategy within two years. Data engineers who want to stay current and find ways to improve productivity, while driving stable data at scale, should implement observability practices in their data engineering platform.

Establishing the right observability for your organization involves bringing the following key capabilities:

• End-to-end visibility at scale: eliminate blind spots and uncover system insights by easily viewing and analyzing your jobs and data pipelines in one single location
• Proactive monitoring and early failure detection: identify potential issues as soon as they arise, before they impact anything downstream
• Troubleshooting and optimization: fix problems to ensure the quality of your outputs and optimize your system's performance to improve operational costs

Read on to see how Lakeflow supports all of these in a single experience.

End-to-End Visibility at Scale into Jobs and Pipelines

Effective observability begins with complete visibility. Lakeflow comes with a variety of out-of-the-box visualizations and unified viewsto help you stay on top of your data pipelines and make sure your entire ETL process is running smoothly.

Fewer Blind Spots with a centralized and granular view of your jobs and pipelines

The Jobs and Pipelines page centralizes access to all your jobs, pipelines, and their run history across the workspace. This unified overview of your runs simplifies the discovery and management of your data pipelines and makes it easier to visualize executions and track trends for more proactive monitoring.

Looking for more information about your Jobs? Just click on any job to go to a dedicated page that features a Matrix Viewand highlights key details like status, duration, trends, warnings, and more. You can:

• easily drill down into a specific Job run for additional insights, such as the graph view to visualize dependencies or point of failure
• zoom in to see the task level(like pipeline, notebook output, etc.) for more details, such as streaming metrics(available in Public Preview).

Lakeflow also offers a dedicated Pipeline Run page where you can easily monitor the status, metrics, and track progress of your pipeline execution across tables.

More insights with visualization of your data at scale

In addition to these unified views, Lakeflow provides historical observability for your workloads to get insights into your usage and trends. Using System Tables, Databricks-managed tables that track and consolidate every job and pipeline created across all workspaces in a region, you can build detailed dashboards and reports to visualize your jobsand pipelines'data at scale. With the recently updated interactive dashboard templatefor Lakeflow System Tables,it's much easier and faster to:

• track execution trends: easily surface insights around job behavior over time for better data-driven decisions
• identify bottlenecks: detect potential performance issues (covered in more detail in the following section)
• cross-reference with billing: improve cost monitoring and avoid billing surprises

System Tables for Jobs and Pipelines are currently in Public Preview.

Visibility extends beyond just the task or job level. Lakeflow's integration with Unity Catalog, Databricks' unified governance solution, helps complete the picture with a visual of your entire data lineage. This makes it easier to trace data flow and dependencies and get the full context and impact of your pipelines and jobs in one single place.
