Properties in application.yml:

hazelcast:
    port: 5702
    kubernetes: false
    timeoutMinutes: 30
    maxSize: 1000
    namespace: default
    serviceName:

Service name can also get from: spring.application.name if property serviceName is empty. At each property show default value and do not require if expected.

Each cache by name can have own properties:

spring.cache:
  <cache name>.expireAfterAccess: 500 # milliseconds
  <cache name>.expireAfterWrite: 1000 # milliseconds
  <cache name>.maximumSize: 10000

Cache using the fast max policy resolving and at put a many entities in one time - the max policy resolver only for each 250 ms.
