Administration
The management console is located under 'Event broker' in the 'Administration' area. It contains three tables: 'Topics', 'Subscribers' and 'Subscriptions'.
All content is read-only, except for the following operations:
-
Topics and subscribers can be manually activated or deactivated using dedicated services.
-
Subscribers that are no longer registered to the broker can be deleted.
The event broker is based on a thread pool mechanism. The maximum number of threads can be defined in the properties file as follows:
# Defines the number of thread pool executors to
# guarantee the publication of asynchronous events.
# The default value is 2
