- def apply(path: Path, maxChunkSize: Int, startingPosition: Long, pollingInterval: FiniteDuration): Source[ByteString, NotUsed]
Scala API: Read the entire contents of a file, and then when the end is reached, keep reading newly appended data.
Scala API: Read the entire contents of a file, and then when the end is reached, keep reading newly appended data. Like the unix command
tail -f
.Aborting the stage can be done by combining with a pekko.stream.KillSwitch
- path
a file path to tail
- maxChunkSize
The max emitted size of the
ByteString
s- startingPosition
Offset into the file to start reading
- pollingInterval
When the end has been reached, look for new content with this interval
