-------------------------------------
Summary: KafkaSink: when init transaction, it take too long to get
a producerId with epoch=0
Key: FLINK-27318
URL: https://issues.apache.org/jira/browse/FLINK-27318
Project: Flink
Issue Type: Improvement
Components: Connectors / Kafka
Affects Versions: 1.14.4
Reporter: Zhengqi Zhang
Attachments: image-2022-04-20-17-34-48-207.png
as we can see, the new KafkaSink aborts all transactions that have been created
by a subtask in a previous run, only return when get a producerId was unused
before(epoch=0). But this can take a long time, especially if the task has been
started and cancelled many times before. In my tests, it even took {*}10
minutes{*}. Is there a better way to solve this problem, or {*}do what
FlinkKafkaProducer did{*}.
