discardBytes
Discards the entities data bytes by running thedataBytes
Source contained in thisentity
.Note: It is crucial that entities are either discarded, or consumed by running the underlying
Source
as otherwise the lack of consuming of the data will trigger back-pressure to the underlying TCP connection (as designed), however possibly leading to an idle-timeout that will close the connection, instead of just having ignored the data.Warning: It is not allowed to discard and/or consume the
entity.dataBytes
more than once as the stream is directly attached to the "live" incoming data source from the underlying TCP connection. Allowing it to be consumable twice would require buffering the incoming data, thus defeating the purpose of its streaming nature. If the dataBytes source is materialized a second time, it will fail with an "stream can cannot be materialized more than once" exception.In future versions, more automatic ways to warn or resolve these situations may be introduced, see issue #18716.
