You must choose a service class when you create an event broker service in
Event broker services are deployed on customer-dedicated software event brokers. This means that your event broker services are completely separated and isolated from other event broker services.
The tables below show the service classes and the most common service-level limits that you may be interested in. For detailed information about other limits, contact SAP.
Regardless of its service class, all event broker services allow you to create and access only one Message VPN. Unless specified on this page, all other limits correspond to the limits for the underlying software event broker as specified in the Service Class Properties table:
The posted limits in the tables below refer to the latest version supported on advanced event mesh. Event broker services utilize a varying number of internal topic subscriptions, clients, queues, and connections based on the configuration of these features:
- Config-Sync
- Clusters and event mesh (DMR)
- Disaster Recovery (DR) using Replication
- VPN Bridges
These internally created topic subscriptions, clients, queues, and connections draw from the posted limit numbers. For example, on an Enterprise 1K event broker service, if a configured feature consumes nine connections, then your event broker service would have another 99,991 connections available.
You can use Broker Manager to find the number of clients, topic subscriptions, queues, and connections that are consumed by the configuration of features on an event broker service. For example, to find the number of clients that were created internally for an event broker service, select Clients > Clients from the navigation bar in Broker Manager.
- With the appropriate account permissions, you can change the message spool size of an existing event broker service 10.0 or later using the scalable message spool sizing feature. For more information, see Adding Scalable Message Spool Size to an Existing Event Broker Service.
- Event broker services prior to version 10.5 may have queue message sizes smaller than those listed in the table below. If you are reaching the maximum queue messages for an existing event broker service, you can upgrade to 10.5.1 and then request to upscale the queue messages. You can view the Max Queue Messages for the event broker service by selecting it in Cluster Manager and then selecting the Configuration tab. See Upgrading Event Broker Services in SAP Integration Suite, Advanced Event Mesh or contact SAP.
