Github user mbalassi commented on the pull request: https://github.com/apache/flink/pull/659#issuecomment-99885222 General comments: * Let us make sure that the names are somewhat consistent with other parts of the code. Made inline comments. * Low watermark concept is "sneaked" into the source interfaces without mentioning it in the description. :) * You use `joda.time` which is inconsistent with other parts of the streaming code. Let us avoid using two time packages. * These changes need documentation, the source behavior is completely changed.
