Hi everyone,

i would like to understand what is the difference between ExchangeQueueListenerService and ExchangeQueueSyncService.
I’ve find some info on edn about the difference between query-base synchro (ExchangeSyncService) and queue-based synchro (ExchangeQueueSyncService or ExchangeQueueListener ?) but I don’t find the real difference between QueueListener and QueueSync.

Hello Vince,

In the synchro by queue, Efficy add/update events in the table SyncQueue each time there are modifications that require to be synced.
Since the sync is bidirectional, we need a service that connects to exchange and fill the same table for the other direction: this is the Listener.
The queue sync is the main service that performs the sync based on events contained in the table.
