Configure Hazelcast to have 1 backup to reduce memory
Currently Hazelcast is configured to have 3 synchronous backups and 3 asynchronous backups. These are separate, meaning there will be 7 copies in the cluster (1 original + 3 sync + 3 async backups). Even if only 1 instance of CPS/NCMP is running, it will have 7 copies in memory. Given that CPS/NCMP is typically only deployed using 1 or 2 instances, the settings are changed to 1 synchronous backup (same as Hazelcast's default configuration). This change has been tested and shown to reduce heap usage by around 100MB during 20K CM-handle registration.
