Data Retention

Coder Agents automatically cleans up old conversation data to manage database growth. Archived conversations and their associated files are periodically purged based on a configurable retention period.

Conversations become eligible for purging only after they are archived. Old conversations can be archived manually, or automatically. See Auto-Archive for how the two controls interact.

Debug run and step cleanup is controlled separately. See Chat Debug Data Retention.

How it works

A background process runs approximately every 10 minutes to remove expired conversation data. Only archived conversations are eligible for deletion — active (non-archived) conversations are never purged.

When an archived conversation exceeds the retention period, Coder deletes it along with its messages, diff statuses, and queued messages. Coder retains an attached file while any conversation references it, regardless of whether the conversation is active or archived. A file that exceeds the retention period becomes eligible for deletion only after no conversations reference it. Conversation and file cleanup operations run in batches of 1,000 rows per cycle.

Configuration

Navigate to the Agents page, open Settings, and select the Behavior tab to configure the conversation retention period. The default is 30 days. Use the toggle to disable retention entirely.

Use the admin API to read or update the value:

What gets deleted

Unarchive safety

Archiving a conversation does not make its attached files eligible for deletion. If you unarchive a conversation before Coder purges it, its attachments remain available, even when the files exceed the retention period.
