--------------------------------------
Summary: Flink JDBC XA connector need to set maxRetries to 0 to
properly working
Key: FLINK-22311
URL: https://issues.apache.org/jira/browse/FLINK-22311
Project: Flink
Issue Type: Bug
Reporter: Maciej Bryński
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.
