loadAndQueueTokenBatch

public void loadAndQueueTokenBatch(@Observes
                                   MessageHolderWithVariants msg)
                            throws IllegalStateException

Receives request for processing a UnifiedPushMessage and loads tokens for devices that match requested parameters from database. Device tokens are loaded in a stream and split to batches of configured size (see SenderConfiguration.batchSize()). Once the pre-configured number of batches (see 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. Additionally it fires BatchLoadedEvent as CDI event (that is translated to JMS event). When all batches were loaded for the given variant, it fires AllBatchesLoadedEvent.

Parameters:

msg - holder object containing the payload and info about the effected variants

Throws:

IllegalStateException
