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> # Optional. defaults to "state"
- 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.
Warning
The above example uses secrets as plain strings. It is recommended to use a secret store for the secrets as described here.
If you wish to use SQL server as an actor state store, append the following to the yaml.
- name: actorStateStore
value: "true"
Spec metadata fields
Field | Required | Details | Example |
---|---|---|---|
connectionString | Y | The connection string used to connect. If the connection string contains the database it must already exist. If the database is omitted a default database named “Dapr” is created. | “Server=myServerName\myInstanceName;Database=myDataBase;User Id=myUsername;Password=myPassword;” |
tableName | N | The name of the table to use. Alpha-numeric with underscores. Defaults to “state” | “table_name” |
keyType | N | The type of key used. Defaults to “string” | “string” |
keyLength | N | The max length of key. Used along with “string” keytype. Defaults to “200” | “200” |
schema | N | The schema to use. Defaults to “dbo” | “dapr” ,“dbo” |
indexedProperties | N | List of IndexedProperties. | ‘[{“column”: “transactionid”, “property”: “id”, “type”: “int”}, {“column”: “customerid”, “property”: “customer”, “type”: “nvarchar(100)”}]’ |
actorStateStore | N | Indicates that Dapr should configure this component for the actor state store (more information). | “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 and in Docker.
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
