---------------------------------
I think it's in a low priority to fix the legacy {{JdbcLookupFunction}}. But
it's welcome to contribute a bug fix.
> The Jdbc-connector's 'lookup.max-retries' option initial value is 1 in
> JdbcLookupFunction

> Key: FLINK-19905

> Project: Flink
> Issue Type: Bug
> Components: Connectors / JDBC
> Affects Versions: 1.11.2, 1.11.3
> Reporter: dalongliu
> Priority: Minor
> Fix For: 1.12.0
>
>
> As describe in FLINK-19684, we should init the begin value to 0 in
> JdbcLookupFunction. The PR only correct the retry value to 0 in
> JdbcRowDataLookupFunction and JdbcBatchingOutputFormat class, maybe the
> contributor forgets to correct it in JdbcLookupFunction class.
