Enable to log all elements that are dropped due to failures (at DEBUG level).
This setting configures the default dispatcher to be used by streams materialized with the ActorMaterializer.
This setting configures the default dispatcher to be used by streams materialized with the ActorMaterializer. This can be overridden for individual parts of the stream topology by using akka.stream.Attributes#dispatcher.
Test utility: fuzzing mode means that GraphStage events are not processed in FIFO order within a fused subgraph, but randomized.
Each asynchronous piece of a materialized stream topology is executed by one Actor that manages an input buffer for all inlets of its shape.
Each asynchronous piece of a materialized stream topology is executed by one Actor that manages an input buffer for all inlets of its shape. This setting configures the initial and maximal input buffer in number of elements for each inlet.
FIXME: Currently only the initialSize is used, auto-tuning is not yet implemented.
Configure the maximum buffer size for which a FixedSizeBuffer will be preallocated.
Configure the maximum buffer size for which a FixedSizeBuffer will be preallocated. This defaults to a large value because it is usually better to fail early when system memory is not sufficient to hold the buffer.
Maximum number of elements emitted in batch if downstream signals large demand.
Leaked publishers and subscribers are cleaned up when they are not used within a given deadline, configured by StreamSubscriptionTimeoutSettings.
Java API: Decides how exceptions from application code are to be handled, unless overridden for specific flows of the stream operations with akka.stream.Attributes#supervisionStrategy.

Limit for number of messages that can be processed synchronously in stream to substream communication

Enable automatic fusing of all graphs that are run.
Enable automatic fusing of all graphs that are run. For short-lived streams this may cause an initial runtime overhead, but most of the time fusing is desirable since it reduces the number of Actors that are created.
(Since version 2.5.0) Turning off fusing is no longer possible with the traversal based materializer
