要求:- 使用spring batch定义远程分区
看起来所有分区都没有执行并行执行。 据我了解,例如,如果gridSize = 3,则所有三个分区都应与从属step(reader \ process \ writer)类并行执行。
Configurations:-
TaskExecutor:-
corePoolSize = 3
maxPoolSize = 20
queueCapacity = 100
gridSize = 3
chunkSize = 10
我已经定义了分区程序类,该类将返回与网格大小相同的executionContext。 ExecutionContext = {PART3 = start = 0,PART1 = start = 0,PART2 = start = 0}
ReaderClass:-
public void beforeStep(StepExecution stepExecution) {
log.info(stepExecution);
}
public Scope read(){
--- some operations---
return new Scope();
}
ProcessClass:-
public Data process(Scope scope){
-- some operations --
return new Data(scope);
}
WriterClass :-
public void write(List<? extends Data> dataItemsSize){
-- some operations --
}

答案 0 :(得分:0)
看起来您正在使用TaskExecutorPartitionHandler
,并根据您的日志,按预期由不同线程(Container-28
,Container-30
,Container-49
)并行执行分区。
要求:-使用spring batch定义远程分区
如果要配置远程分区,则需要使用MessageChannelPartitionHandler
。您可以找到有关如何使用它的示例here。
