class PersistentBuffer[T] extends PersistentBufferBase[T, T]

Persists all incoming upstream element to a memory mapped queue before publishing it to downstream consumer.

Emits when one of the inputs has an element available

Does not Backpressure upstream when downstream backpressures, instead buffers the stream element to memory mapped queue

Completes when upstream completes

Cancels when downstream cancels
