Local Configuration setting for _maxBatchSize.value

IrwanAfandiGDP — Fri, 02 Jan 2026 14:45:42 GMT

Hello... could someone help me to give an example how to change the value of

_maxBatchSize.value

(the default value is 1000 and I want 20000). The documentation said like this, but I'm still confused how to implement it on LocalConfiguration.

My second question, how do I know that the iteration is the last batch iteration (iteration comes from

@ElementListener

) on

@AfterGroup

? Because I want to run my function after all the data is loaded. Thank you

Hi @Mohamad Irwan Afandi,

For the local-configuration.properties, you'll find some samples below:

- https://github.com/Talend/connectors-se/blob/master/marketo/src/main/resources/TALEND-INF/local-configuration.properties

- https://github.com/Talend/connectors-se/blob/master/salesforce/src/main/resources/TALEND-INF/local-configuration.properties

For you 2nd question, you cannot know it in @AfterGroup... for that you may use the @PreDestroy annotation (see

https://talend.github.io/component-runtime/main/1.33.0/component-execution.html) of

connectors' lifecycle. But be aware that implementing some actions like this in the @PreDestroy is not officially

supported (best effort) in Cloud environments and should only be used to release some acquired resources...

Best regards
