  38. final def stream[T](a: StreamingDBIO[_, T], bufferNext: Boolean): DatabasePublisher[T]

    Like stream(StreamingAction) but you can disable pre-buffering of the next row by setting bufferNext = false.

    Like stream(StreamingAction) but you can disable pre-buffering of the next row by setting bufferNext = false. The ResultSet will not advance to the next row until you request() more data. This allows you to process LOBs asynchronously by requesting only one single element at a time after processing the current one, so that the proper sequencing is preserved even though processing may happen on a different thread.

  39. final def stream[T](a: DBIOAction[_, Streaming[T], Nothing]): DatabasePublisher[T]

    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).
