### Query engine
flink
### Question
I used flink API to write data
By flink local mode, the speed is more than 20000 record/s
but i change to flink perjob mode, the speed is under 50 record/s
Same code, only changed submit mode
Code like :
SingleOutputStreamOperator<RowData> map = source.filter(new
RichFilterFunction<Record>() {
@Override
public boolean filter(Record value) throws Exception {
return filterRecord(value);
}
}).map(new RichMapFunction<Record, RowData>() {
@Override
public RowData map(Record value) throws Exception {
return mappingAndConvert(value);
}
});
FlinkSink.Builder sinkBuilder = FlinkSink.forRowData(map)
.table(table)
.tableLoader(TableLoader.fromHadoopTable(tableLocation,
getHadoopConf(icebergConfig)))
.writeParallelism(parallelism+10)
.equalityFieldColumns(equalityFiledColumns)
.overwrite(overwrite);
if (Objects.nonNull(writeFileSize) && writeFileSize > 0) {
sinkBuilder.set("target-file-size-bytes",
String.valueOf(writeFileSize));
}
sinkBuilder.append();
