ActorAttributes

Enables additional low level troubleshooting logging at DEBUG log level

Use factory method #debugLogging to create.

Configures the dispatcher to be used by streams.

Use factory method ActorAttributes#dispatcher to create instances.

Test utility: fuzzing mode means that GraphStage events are not processed in FIFO order within a fused subgraph, but randomized.

Use factory method #fuzzingMode to create.

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.

Use factory method #maxFixedBufferSize to create.

Maximum number of elements emitted in batch if downstream signals large demand.

Use factory method #outputBurstLimit to create.

Defines a timeout for stream subscription and what action to take when that hits.

Use factory method streamSubscriptionTimeout to create.

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

Use factory method #syncProcessingLimit to create.

Java API

Configures log() operator log-levels to be used when logging. Logging a certain operation can be completely disabled by using Attributes#logLevelOff.

Scala API: Decides how exceptions from user are to be handled.

Operators supporting supervision strategies explicitly document that they do so. If a operator does not document support for these, it should be assumed it does not support supervision.

Java API: Decides how exceptions from application code are to be handled.

Operators supporting supervision strategies explicitly document that they do so. If a operator does not document support for these, it should be assumed it does not support supervision.
