# Storage policy

Configuration settings for storage policies in QuestDB Enterprise.

:::note

Storage policy is [Enterprise](/enterprise/) only.

:::

Storage policies automate partition lifecycle management: they convert older
partitions to Parquet locally and drop local copies on a schedule. These
settings control the scan interval, retry behavior, and worker threads for the
storage policy engine.

For details, see the
[storage policy concept](/docs/concepts/storage-policy/) page.

## storage.policy.check.interval

- **Default**: `5m`
- **Reloadable**: no

How often QuestDB scans for partitions to process.

- **Reloadable**: no

Number of idle worker-loop iterations before a storage policy worker naps.

## storage.policy.worker.sleep.threshold

- **Default**: `500`
- **Reloadable**: no

Number of idle worker-loop iterations before a storage policy worker sleeps.

## storage.policy.worker.sleep.timeout

- **Default**: `100ms`
- **Reloadable**: no

Sleep duration when a storage policy worker has no tasks to process.

## storage.policy.worker.yield.threshold

- **Default**: `10`
