This is configurable. +- If no Kinesis checkpoint info exists when the input DStream starts, it will start either from the oldest record available (InitialPositionInStream.TRIM_HORIZON) or from the latest tip (InitialPositionInStream.LATEST). This is configurable. - InitialPositionInStream.LATEST could lead to missed records if data is added to the stream while no input DStreams are running (and no checkpoint info is being stored). - InitialPositionInStream.TRIM_HORIZON may lead to duplicate processing of records where the impact is dependent on checkpoint frequency and processing idempotency. http://git-wip-us.apache.org/repos/asf/spark/blob/024482bf/docs/streaming-programming-guide.md ---------------------------------------------------------------------- diff --git a/docs/streaming-programming-guide.md b/docs/streaming-programming-guide.md index 4d1932b..5d67a0a 100644 --- a/docs/streaming-programming-guide.md +++ b/docs/streaming-programming-guide.md @@ -158,7 +158,7 @@ JavaReceiverInputDStream<String> lines = jssc.socketTextStream("localhost", 9999 {% endhighlight %} This `lines` DStream represents the stream of data that will be received from the data -server.
