RethinkDB binding spec

Detailed documentation on the RethinkDB binding component

配置

The RethinkDB state store supports transactions which means it can be used to support Dapr actors. Dapr persists only the actor’s current state which doesn’t allow the users to track how actor’s state may have changed over time.

To enable users to track change of the state of actors, this binding leverages RethinkDB’s built-in capability to monitor RethinkDB table and event on change with both the old and new state. This binding creates a subscription on the Dapr state table and streams these changes using the Dapr input binding interface.

To setup RethinkDB statechange binding create a component of type bindings.rethinkdb.statechange. 请参阅本指南，了解如何创建和应用绑定配置。
