Piotr Nowojski updated FLINK-7210: ---------------------------------- Description: To implement exactly-once sink there is a re-occurring pattern for doing it - two phase commit algorithm. It is used both in `BucketingSink` and in `Pravega` sink and it will be used in `Kafka 0.11` connector. It would be good to extract this common logic into one class, both to improve existing implementation (for exampe `Pravega`'s sink doesn't abort interrupted transactions) and to make it easier for the users to implement their own custom exactly-once sinks. (was: To implement exactly-once sink there is a re-occurring pattern for doing it - two phase commit algorithm.
