1.  final case class BackPressure(bufferSize: Int) extends OverflowStrategy[Nothing] with Product with Serializable

   A OverflowStrategy specifying that on reaching the maximum size, the pipeline should try to apply back-pressure (i.e.

   A OverflowStrategy specifying that on reaching the maximum size, the pipeline should try to apply back-pressure (i.e. it should try delaying the data source in producing more elements, until the the consumer has drained the buffer and space is available).

   bufferSize

   specifies how many events our buffer can hold before overflowing

2.  final case class ClearBuffer(bufferSize: Int) extends Evicted[Nothing] with Product with Serializable

   A OverflowStrategy specifying that on reaching the maximum size, the current buffer should be dropped completely to make room for new events.

   A OverflowStrategy specifying that on reaching the maximum size, the current buffer should be dropped completely to make room for new events.

   bufferSize

   specifies how many events our buffer can hold before overflowing

3.  final case class ClearBufferAndSignal[A](bufferSize: Int, onOverflow: (Long) => Coeval[Option[A]]) extends Evicted[A] with Product with Serializable

   A OverflowStrategy specifying that on reaching the maximum size, the current buffer should be dropped completely to make room for new events.

   A OverflowStrategy specifying that on reaching the maximum size, the current buffer should be dropped completely to make room for new events.

   The given onOverflow function get be used for logging the event and for sending a message to the downstream consumers to inform them of dropped messages. The function can return None in which case no message is sent and thus you can use it just to log a warning.

   bufferSize

   specifies how many events our buffer can hold before overflowing

   onOverflow

   is a function that can get called on overflow with a number of messages that were dropped, a function that builds a new message that will be sent to downstream.

4.  final case class DropNew(bufferSize: Int) extends Evicted[Nothing] with Product with Serializable

   A OverflowStrategy specifying that on reaching the maximum size, the pipeline should begin dropping incoming events until the buffer has room in it again and is free to process more elements.

   A OverflowStrategy specifying that on reaching the maximum size, the pipeline should begin dropping incoming events until the buffer has room in it again and is free to process more elements.

   bufferSize

   specifies how many events our buffer can hold before overflowing

5.  final case class DropNewAndSignal[A](bufferSize: Int, onOverflow: (Long) => Coeval[Option[A]]) extends Evicted[A] with Product with Serializable

   A OverflowStrategy specifying that on reaching the maximum size, the pipeline should begin dropping incoming events until the buffer has room in it again and is free to process more elements.

   A OverflowStrategy specifying that on reaching the maximum size, the pipeline should begin dropping incoming events until the buffer has room in it again and is free to process more elements.

   The given onOverflow function get be used for logging the event and for sending a message to the downstream consumers to inform them of dropped messages. The function can return None in which case no message is sent and thus you can use it just to log a warning.

   bufferSize

   specifies how many events our buffer can hold before overflowing.

   onOverflow

   is a function that can get called on overflow with a number of messages that were dropped, a function that builds a new message that will be sent to downstream. If it returns None, then no message gets sent to downstream.

6.  final case class DropOld(bufferSize: Int) extends Evicted[Nothing] with Product with Serializable

   A OverflowStrategy specifying that on reaching the maximum size, the currently buffered events should start being dropped in a FIFO order, so the oldest events from the buffer will be dropped first.

   A OverflowStrategy specifying that on reaching the maximum size, the currently buffered events should start being dropped in a FIFO order, so the oldest events from the buffer will be dropped first.

   bufferSize

   specifies how many events our buffer can hold before overflowing

7.  final case class DropOldAndSignal[A](bufferSize: Int, onOverflow: (Long) => Coeval[Option[A]]) extends Evicted[A] with Product with Serializable

   onOverflow

   is a function that can get called on overflow with a number of messages that were dropped, a function that builds a new message that will be sent to downstream. If it returns None, then no message gets sent to downstream.

8.  sealed abstract class Evicted[A] extends Synchronous[A]

   A sub-category of overflow strategies that are synchronous and that represent eviction policies, meaning that on buffer overflows events start being dropped.

9.  final case class Fail(bufferSize: Int) extends Synchronous[Nothing] with Product with Serializable

   A OverflowStrategy specifying that on reaching the maximum size, the pipeline should cancel the subscription and send an onError to the observer(s) downstream.

   A OverflowStrategy specifying that on reaching the maximum size, the pipeline should cancel the subscription and send an onError to the observer(s) downstream.

   bufferSize

   specifies how many events our buffer can hold before overflowing

10.  sealed abstract class Synchronous[+A] extends OverflowStrategy[A]

    A category of OverflowStrategy for buffers that can be used synchronously, without worrying about back-pressure concerns.
