What is replacement of EventTimeSourceFunction (Flink 0.10.x) in Flink 1.x? -


i trying migrate slidingarrivalcount.scala example based on flink 0.10.1 flink 1.1.1.

the taxiridesource data stream source used in example implements org.apache.flink.streaming.api.functions.source.eventtimesourcefunction interface, no longer provided flink 1.x.

how can port taxiridesource flink 1.x?

since flink 1.0.0, sourcefunction can operate in event time mode, i.e., have interfaces in place so.

source functions implement eventtimesourcefunction can upgraded flink 1.x, replacing eventtimesourcefunction sourcefunction.
