io.strimzi.kafka.oauth.services.Sessions

public class Sessions
extends java.lang.Object

Sessions entries should automatically get cleared as KafkaPrincipals for the sessions get garbage collected by JVM. The size of `activeSessions` at any moment in time should be about the number of currently active sessions. They may also get removed by broker-side plugins like custom authorizers when it is determined that the token has expired.
