* <p>Device tokens are loaded in a stream and split to batches of configured size (see {@link

* SenderConfiguration#batchesToLoad()}) is reached, this method resends message to the same queue
* it took the request from, so that the transaction it worked in is split and further processing
* may continue in next transaction.
*
* <p>Additionally it fires {@link BatchLoadedEvent} as CDI event (that is translated to JMS
* event) that helps {@link MetricsCollector} to track how many batches were loaded. When all
* batches were loaded for the given variant, it fires {@link AllBatchesLoadedEvent}.
