The 5 pillars of data observability

Data observability can be broken down into 5 main pillars:

• Freshness
• Distribution
• Volume
• Schema
• Lineage

Freshness

Freshness refers to the timeliness of data, i.e. how up-to-date and recent given data is at any point in time. This pillar enables businesses to monitor the latency of their data flow, ensuring that the information being used for decision-making is as current as possible.

Distribution

Distribution focuses on understanding how data is being transmitted and moved across various data sources. It involves:

• Tracking the flow of data through its entire journey, from source to destination.
• Identifying any potential bottlenecks or failures.

Volume

Volume refers to the size of data being processed and stored by an organization. This pillar enables you to monitor your storage capacity and cost — and identify any issues with data scaling.

Schema

Schema refers to the structure and organization of data, including its format, type, and relationships. This pillar helps you ensure data consistency across different systems and identify any discrepancies or errors.

Lineage

Lineage refers to the history and origin of data, tracking where it came from and how it has been transformed throughout its journey. Data lineage allows you to best understand the reliability and accuracy of your data, as well as identify any potential data quality issues.
