+
+## Overview
+
+Data Observability analyzes your Spark and Databricks jobs, and your Snowflake, BigQuery, and Trino queries, to surface specific recommendations for reducing cost and improving performance — for example, right-sizing cluster configuration or rewriting an inefficient query.
+
+Each recommendation includes an estimated cost or duration impact. Some job recommendations can be applied directly as a code change through Bits AI.
+
+## View recommendations
+
+Recommendations for jobs and clusters appear inline in [Jobs Monitoring][1] job and cluster tables. Select a job or cluster with an available recommendation to open its recommendation details in a side panel.
+
+Each recommendation has a status you can update as you triage it:
+
+| Status | Description |
+|---|---|
+| {{< ui >}}For Review{{< /ui >}} | The default status for a new recommendation. |
+| {{< ui >}}Reviewed{{< /ui >}} | You've looked at the recommendation but haven't acted on it yet. |
+| {{< ui >}}Ignored{{< /ui >}} | You've decided not to act on this recommendation. |
+| {{< ui >}}Resolved{{< /ui >}} | You've applied the recommendation. |
+
+For recommendations that include a code change, click {{< ui >}}Fix with Bits{{< /ui >}} to have Bits AI apply the change for you.
+
+**Note**: Whether Data Observability generates recommendations for your Snowflake, BigQuery, Databricks, or Trino workloads depends on which recommenders your organization has enabled — contact your Datadog representative to confirm which are active for your account.
