+description: Detailed information on the AWS DynamoDB state store component
+---
+
+## Component format
+
+To setup a DynamoDB state store create a component of type `state.dynamodb`. See [this guide]({{< ref "howto-get-save-state.md#step-1-setup-a-state-store" >}}) on how to create and apply a state store configuration.
+
+```yaml
+apiVersion: dapr.io/v1alpha1
+kind: Component
+metadata:
+  name: <NAME>
+  namespace: <NAMESPACE>
+spec:
+  type: state.dynamodb
+  version: v1
+  metadata:
+  - name: table
+    value: "mytable"
+  - name: accessKey
+    value: "abcd"
+  - name: secretKey
+    value: "abcd"
+  - name: endpoint
+    value: "http://localhost:8080"
+  - name: region
+    value: "eu-west-1"
+  - name: sessionToken
+    value: "abcd"
+```
+
+{{% alert title="Warning" color="warning" %}}
+The above example uses secrets as plain strings. It is recommended to use a secret store for the secrets as described [here]({{< ref component-secrets.md >}}).

+## Spec metadata fields
+
+| Field              | Required | Details | Example |
+|--------------------|:--------:|---------|---------|
+| table              | Y  | name of the DynamoDB table to use  | `"mytable"`
+| accessKey          | N  | ID of the AWS account with appropriate permissions to SNS and SQS. Can be `secretKeyRef` to use a secret reference  | `"AKIAIOSFODNN7EXAMPLE"`
+| secretKey          | N  | Secret for the AWS user. Can be `secretKeyRef` to use a secret reference   |`"wJalrXUtnFEMI/K7MDENG/bPxRfiCYEXAMPLEKEY"`
+| region             | N  | The AWS region to the instance. See this page for valid regions: https://docs.aws.amazon.com/AmazonRDS/latest/UserGuide/Concepts.RegionsAndAvailabilityZones.html. Ensure that DynamoDB are available in that region.| `"us-east-1"`
+| endpoint          | N  |AWS endpoint for the component to use. Only used for local development. The `endpoint` is unncessary when running against production AWS   | `"http://localhost:4566"`
+| sessionToken      | N  |AWS session token to use.  A session token is only required if you are using temporary security credentials. | `"TOKEN"`
