Summary: Refactor MQTT subscription persistence
Key: ARTEMIS-5499
URL: https://issues.apache.org/jira/browse/ARTEMIS-5499
Project: ActiveMQ Artemis
Issue Type: Bug
Reporter: Justin Bertram
Assignee: Justin Bertram
The current way the broker persists MQTT subscription data has the potential to
starve the broker of threads. It also leads to timeouts like this:
{noformat}
java.lang.IllegalStateException: AMQ850000: Unable to store MQTT state within
given timeout: 5000ms

org.apache.activemq.artemis.core.protocol.mqtt.MQTTStateManager.storeSessionState(MQTTStateManager.java:192)

org.apache.activemq.artemis.core.protocol.mqtt.MQTTSubscriptionManager.addSubscriptions(MQTTSubscriptionManager.java:334){noformat}
