# Inactive Tables in Storage Account

## Explanation

Tables with no read or write activity often represent deprecated applications, obsolete telemetry, or abandoned development artifacts. Retaining inactive tables increases storage costs and operational complexity. Regularly auditing and cleaning up unused tables helps maintain a streamlined, cost-effective storage environment.

## Relevant Billing Model

Azure Table Storage charges for stored data per GB and separately for read, write, and delete operations. Tables incur ongoing storage costs even if no activity occurs, contributing to unnecessary baseline expenses.

## Detection

- Identify Azure Table Storage tables with no read or write operations over a defined lookback period

- Review table creation dates, metadata, and ownership tags to assess relevance and intended retention

- Check for compliance, legal hold, or audit requirements before initiating deletions or exports

- Evaluate whether table contents require archival, and plan export strategies where needed

- Validate findings with application owners, data stewards, or governance teams before proceeding

## Remediation

Delete tables confirmed to be redundant or obsolete. If long-term retention is required, export the table contents (e.g., to CSV or JSON format) and store them in lower-cost services like Azure Blob Storage Archive tier. Incorporate tagging and lifecycle management practices to prevent reaccumulation of unused tables.
