----------------------------------

             Summary: parameters 'maxRetryTimes' can not work in JDBCUpsertTableSink
                 Key: FLINK-16281
                 URL: https://issues.apache.org/jira/browse/FLINK-16281
             Project: Flink
          Issue Type: Bug
          Components: Table SQL / Ecosystem
    Affects Versions: 1.10.0
            Reporter: Leonard Xu
             Fix For: 1.10.1, 1.11.0


parameters 'maxRetryTimes' can not work in JDBCUpsertTableSink,

 

because PreparedStatement will clear batchedArgs info after first 

call function executeBatchInternal() as follows:

 
{code:java}
//com.mysql.jdbc.PreparedStatement
finally {
    this.statementExecuting.set(false);
    clearBatch();
}

// clearBatch() function implement
public void clearBatch() throws SQLException {
 synchronized (checkClosed().getConnectionMutex()) {
 if (this.batchedArgs != null) {
 this.batchedArgs.clear();
 }
 }
}
{code}
and the next time to call function executeBatchInternal() can not go on because this piece code:

 

 
{code:java}
//com.mysql.jdbc.PreparedStatement
if (this.batchedArgs == null || this.batchedArgs.size() == 0) {
    return new long[0];
}
{code}
