Batch Handler

Updated: March 18, 2024


Batch Handler is a concept introduced in Nuxeo Platform 10.1 Fast Track version, which consists in allowing custom upload behaviour to all the batches.

The previous behaviour is now a provider, which we call "Default". When needed, you can customize the Transient Store to manage your uploads (e.g., Use a 3rd party cloud provider storage).


void initialize(String name, Map<String, String> properties);
String getName();
Batch newBatch(String batchId);
Batch getBatch(String batchId);
boolean completeUpload(String batchId, String fileIdx, BatchFileInfo fileInfo)

Contributing Your Own Handler

To implement your own handler you need to implement the interface BatchHandler and register it through the extension point handlers in org.nuxeo.ecm.automation.server.BatchManager.


<extension target="org.nuxeo.ecm.automation.server.BatchManager" point="handlers">
    <property name="transientStore">${backingTransientStore}</property>
    <property name="key1">value1</property>
    <property name="key2">value2</property>
    <property name="keyN">valueN</property>

A S3DirectBatchHandler is provided and configured in the Amazon S3 Online Storage addon.
