Sets the ActiveMQ broker URL. Use this property to configure the broker connection, including prefetch policy settings.
- **`ACTIVEMQ_URL_PARAMS` with `jms.prefetchPolicy.all` (Spring Boot/ActiveMQ):**
Overrides the default ActiveMQ connection options of broker URL by including prefetch policy settings.
It controls how many messages are prefetched from the queue by each consumer before processing. A higher prefetch value can
improve throughput but may increase memory usage. Note that raising this number might lead to starvation of concurrent consumers!
**Default:** `tcp://localhost:61616` (prefetch policy default is 1000 for queues)
**Default:** `?jms.watchTopicAdvisories=false` (prefetch policy default is 1000 for queues)
**Note:** The T-Engines consumers should be considered as slow consumers. Processing each message can take a significant amount of time.
So, the prefetch size should be correctly set (based on performance tests) to distribute the messages equally across the nodes
