Dapr enables per state set request time-to-live (TTL). This means that applications can set time-to-live per state stored, and these states cannot be retrieved after expiration.

For [supported state stores]({{< ref supported-state-stores >}}), you simply set the `ttlInSeconds` metadata when publishing a message. Other state stores will ignore this value. For some state stores, you can specify a default expiration on a per-table/container basis.

## Native state TTL support

When state TTL has native support in the state store component, Dapr forwards the TTL configuration without adding any extra logic, maintaining predictable behavior. This is helpful when the expired state is handled differently by the component.

When a TTL is not specified, the default behavior of the state store is retained.

## Persisting state (ignoring an existing TTL)

To explicitly persist a state (ignoring any TTLs set for the key), specify a `ttlInSeconds` value of `-1`.

## Supported components

Refer to the TTL column in the [state store components guide]({{< ref supported-state-stores >}}).

## Example

You can set state TTL in the metadata as part of the state store set request:

<!--python-->

```python
#dependencies

from dapr.clients import DaprClient

#code

DAPR_STORE_NAME = "statestore"

with DaprClient() as client:
        client.save_state(DAPR_STORE_NAME, "order_1", str(orderId), state_metadata={
            'ttlInSeconds': '120'
        }) 

```

To launch a Dapr sidecar and run the above example application, you'd then run a command similar to the following:

```bash
dapr run --app-id orderprocessing --app-port 6001 --dapr-http-port 3601 --dapr-grpc-port 60001 -- python3 OrderProcessingService.py
```

    } 
});
```
