Map configuration

This is used to configure how map data is stored within the cluster, either individual named maps or a cluster-wide default.

Maximum size and eviction

Maximum size policies include:

• PER_NODE
• PER_PARTITION
• USED_HEAP_SIZE
• USED_HEAP_PERCENTAGE
• FREE_HEAP_SIZE
• FREE_HEAP_PERCENTAGE

Eviction policies include:

• LRU: Least Recently Used
• LFU: Least Frequently Used
• NONE

<map name="default">
 <max-size policy="PER_NODE">10</max-size>
 <eviction-policy>LFU</eviction-policy>
 <eviction-percentage>20</eviction-percentage>
</map>

config.getMapConfig("default")
 .setMaxSizeConfig(new MaxSizeConfig(10, MaxSizePolicy.PER_NODE))
 .setEvictionPolicy(EvictionPolicy.LFU)
 .setEvictionPercentage(20);

Backup copies

Backup = Synchronous copies

Async = Asynchronous copies

Total copies = 1 Main + Backup + Async

<map name="default">
 <backup-count>1</backup-count>
 <async-backup-count>1</async-backup-count...
