> Use PulsarAdmin to make PulsarSink transaction commits idempotent during

> ---------------------------------------------------------------------------------
>
> Key: FLINK-41194
> URL: https://issues.apache.org/jira/browse/FLINK-41194
> Project: Flink
> Issue Type: Bug
> Components: Connectors / Pulsar
> Affects Versions: 2.0.0
> Reporter: Yubiao Feng
> Priority: Major
> Labels: pull-request-available
>
> The Pulsar sink currently retries transaction commits during checkpoint
> recovery without checking the transaction state first. If the transaction was
> already committed before the recovery attempt, committing it again may fail
> with an exception and cause recovery to fail.
> Restore the {{PulsarAdmin}} construction support removed by
> [FLINK-32938|https://github.com/apache/flink-connector-pulsar/pull/59],
> including the admin URL configuration.
> Before committing a transaction, use {{PulsarAdmin}} to inspect the latest
> published message state:
> * If the transaction is still uncommitted, commit it.
> * If it has already been committed, mark the request as already committed.
> * If it has been aborted, fail the request with a known reason.
> * Retry when the transaction state cannot be queried temporarily.
> This makes PulsarSink transaction commits idempotent during checkpoint
> recovery.
