SQL Server

Detailed information on the SQL Server state store component

Component format

To setup SQL Server state store create a component of type state.sqlserver. See this guide on how to create and apply a state store configuration.

apiVersion: dapr.io/v1alpha1
kind: Component
metadata:
  name: <NAME>
  namespace: <NAMESPACE>
spec:
  type: state.sqlserver
  version: v1
  metadata:
  - name: connectionString
    value: <REPLACE-WITH-CONNECTION-STRING> # Required.
  - name: tableName
    value: <REPLACE-WITH-TABLE-NAME>  # Required.
  - name: keyType
    value: <REPLACE-WITH-KEY-TYPE>  # Optional. defaults to "string"
  - name: keyLength
    value: <KEY-LENGTH> # Optional. defaults to 200. Yo be used with "string" keyType
  - name: schema
    value: <SCHEMA> # Optional. defaults to "dbo"
  - name: indexedProperties
    value: <INDEXED-PROPERTIES> # Optional. List of IndexedProperties.

If you wish to use Redis as an actor state store, append the following to the yaml.

  - name: actorStateStore
    value: "true"

Create Azure SQL instance

Follow the instructions from the Azure documentation on how to create a SQL database. The database must be created before Dapr consumes it.

Note: SQL Server state store also supports SQL Server running on VMs.

In order to setup SQL Server as a state store, you need the following properties:

  • Connection String: the SQL Server connection string. For example: server=localhost;user id=sa;password=your-password;port=1433;database=mydatabase;
  • Schema: The database schema to use (default=dbo). Will be created if does not exist
  • Table Name: The database table name. Will be created if does not exist
  • Indexed Properties: Optional properties from json data which will be indexed and persisted as individual column

Create a dedicated user

When connecting with a dedicated user (not sa), these authorizations are required for the user - even when the user is owner of the desired database schema:

  • CREATE TABLE
  • CREATE TYPE
