----------------------------------
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}
