----------------------------------------
[~syhily] What are your thoughts on this one?
> Data loss in pulsar source when using shared mode
> -------------------------------------------------
>
> Key: FLINK-24733
> URL: https://issues.apache.org/jira/browse/FLINK-24733
> Project: Flink
> Issue Type: Bug
> Components: Connectors / Pulsar
> Affects Versions: 1.14.0
> Reporter: wang shengzhi
> Priority: Major
>
> Description：
> Noticed that when using Flink-connector-pulsar with Shared mode (default
> mode), some messages are lost.
> Details：
> When a topic partition does not receive message for more than 10s
> (pulsar.source.maxFetchTime), the next coming message will be dropped by
> source.
> In stream applications, this situation which there is no data for more than
> 10s is very common. So this bug will cause data loss.
