  1. abstract def close(): Unit

    Permalink

    Free all resources allocated by Slick for this Database, blocking the current thread until everything has been shut down.

    Free all resources allocated by Slick for this Database, blocking the current thread until everything has been shut down.

    Backend implementations which are based on a naturally blocking shutdown procedure can simply implement this method and get shutdown as an asynchronous wrapper for free. If the underlying shutdown procedure is asynchronous, you should implement shutdown instead and wrap it with Await.result in this method.

    streaming

    Permalink

    Create a Publisher for Reactive Streams which, when subscribed to, will run the specified DBIOAction and return the result directly as a stream without buffering everything first.

    Create a Publisher for Reactive Streams which, when subscribed to, will run the specified DBIOAction and return the result directly as a stream without buffering everything first. This method is only supported for streaming actions.

    The Publisher itself is just a stub that holds a reference to the action and this Database. The action does not actually start to run until the call to onSubscribe returns, after which the Subscriber is responsible for reading the full response or cancelling the Subscription. The created Publisher can be reused to serve a multiple Subscribers, each time triggering a new execution of the action.

    For the purpose of combinators such as cleanup which can run after a stream has been produced, cancellation of a stream by the Subscriber is not considered an error. For example, there is no way for the Subscriber to cause a rollback when streaming the results of someQuery.result.transactionally.

    When using a JDBC back-end, all onNext calls are done synchronously and the ResultSet row is not advanced before onNext returns. This allows the Subscriber to access LOB pointers from within onNext. If streaming is interrupted due to back-pressure signaling, the next row will be prefetched (in order to buffer the next result page from the server when a page boundary has been reached).
