Enum PunctuationType
- All Implemented Interfaces:
Serializable
,Comparable<PunctuationType>
,Constable
public enum PunctuationType extends Enum<PunctuationType>
Controls what notion of time is used for punctuation scheduled via
ProcessorContext.schedule(Duration, PunctuationType, Punctuator)
schedule}:
- STREAM_TIME - uses "stream time", which is advanced by the processing of messages
in accordance with the timestamp as extracted by the
TimestampExtractor
in use. NOTE: Only advanced if messages arrive - WALL_CLOCK_TIME - uses system time (the wall-clock time),
which is advanced at the polling interval (
StreamsConfig.POLL_MS_CONFIG
) independent of whether new messages arrive. NOTE: This is best effort only as its granularity is limited by how long an iteration of the processing loop takes to complete
