> Hi,
> We're using XA connector from Flink 1.13 in one of our projects and we were
> able to create duplicates of records during write to Oracle.
> The reason was that default MAX_RETRIES in JdbcExecutionOptions is 3 and this
> can cause duplicates in DB.
> I think we should at least mention this in docs or even validate this option
> when creating XA Sink.
> In documentation we're using defaults.
