Execution modes:

Name Description
ASYNC Runs asynchronously on all of the shards.
ASYNC_LOCAL Runs asynchronously but only on the current shard that generated the event.
SYNC Runs synchronously only on the same shard that generated the event.
Note:
If you call register() without specifying an execution mode, it will default to ASYNC.

Parameters

mode ExecutionMode The execution mode to use (ASYNC/ASYNC_LOCAL/SYNC)
onRegister OnRegisteredOperation Register callback that will be called on each shard upon register
onUnregistered OnUnregisteredOperation Unregister callback that will be called on each shard upon unregister
