Execution context and Job Repository

Hi,

I have a question about the Execution context that you can put stuff into if you want subsequent steps in your job to access it, like so...

Code:

---

ExecutionContext jobExecutionContext = getStepExecution()getExecutionContext(); // get context obj from SB

jobExecutionContext.put("agentsVO", agentVOs); // put my obj in context

---

Is it true that SB will persist my Value object (agentsVO in this example) to the job repository in the database? And if so will it be a performance hit if the Value object is too large?

Thanks in advance for any help.

ExecutionContext persists your agentVOs into a ConcurrentHashMap. Doesn't look like it goes into the datasource.

public void put(String key, Object value) {
if (value != null) {
Assert.isInstanceOf(Serializable.class, value, "Value: [ " + value + "must be serializable.");
Object result = map.put(key, value);
dirty = result==null || result!=null && !result.equals(value);
}
else {
Object result = map.remove(key);
dirty = result!=null;
}
}
