RethinkDB
配置
To setup RethinkDB state store, create a component of type state.rethinkdb
. See the how-to guide to create and apply a state store configuration.
apiVersion: dapr.io/v1alpha1
kind: Component
metadata:
name: <NAME>
namespace: <NAMESPACE>
spec:
type: state.rethinkdb
version: v1
metadata:
- name: address
value: <REPLACE-RETHINKDB-ADDRESS> # Required, e.g. 127.0.0.1:28015 or rethinkdb.default.svc.cluster.local:28015).
- name: database
value: <REPLACE-RETHINKDB-DB-NAME> # Required, e.g. dapr (alpha-numerics only)
- name: table
value: # Optional
- name: username
value: <USERNAME> # Optional
- name: password
value: <PASSWORD> # Optional
- name: archive
value: bool # Optional (whether or not store should keep archive table of all the state changes)
Warning
以上示例将密钥明文存储, It is recommended to use a secret store for the secrets, as described here.If you wish to use RethinkDB as an actor store, append the following to the YAML.
- name: actorStateStore
value: "true"
RethinkDB state store supports transactions, so it can be used to persist Dapr Actor state. By default, the state will be stored in table named daprstate
in the specified database.
此外,如果可选的 archive
元数据被设置为 true
,在每个状态改变时,RethinkDB 状态存储将在 daprstate_archive
表中记录带有时间戳的状态存储。 这允许对 Dapr 管理的状态进行时间序列分析。
