Solution 1: Replicas and Dynamic participantId - still using cache

Changes in Participant intermediary:

• UUID participantId will be generated in memory instead to fetch it in properties file.
• consumerGroup will be generated in memory instead to fetch it in properties file.

...

Solution 3: Replicas and Database support - no cache

Changes in Participant intermediary:

• Redesign TimeOut scenario: Participant has the responsibility to stop the thread in execution after a specific time.
• Add client support for database (MariaDB or PostgreSQL).
• Add mock database for Unit Tests.
• Refactor CacheProvider to ParticipantProvider to support insert/update, intermediary-participant with transactions.
• Refactor Intermediary to use insert/update of ParticipantProvider.
• Refactor Participants that are using own HashMap in memory (Policy Participant saves policy and policy type in memory)

Changes in Participant:

• Add @EnableJpaRepositories and @EntityScan in Application:

• 
  

  Code Block
  language java title Application
  @SpringBootApplication @EnableJpaRepositories({ "org.onap.policy.clamp.acm.participant.intermediary.persistence.repository" }) @ComponentScan({ "org.onap.policy.clamp.acm.participant.sim", "org.onap.policy.clamp.acm.participant.intermediary" }) @EntityScan({ "org.onap.policy.clamp.acm.participant.intermediary.persistence.concepts" }) @ConfigurationPropertiesScan("org.onap.policy.clamp.acm.participant.sim.parameters") public class Application { public static void main(String[] args) { SpringApplication.run(Application.class, args); } }

  
  

• Add db connection in properties file and properties file for tests:

spring:
  security:
    user:
      name: participantUser
      password: zb!XztG34
  mvc:
    converters:
      preferred-json-mapper: gson
  datasource:
    url: jdbc:mariadb://${mariadb.host:localhost}:${mariadb.port:3306}/participantsim
    driverClassName: org.mariadb.jdbc.Driver
    username: policy
    password: P01icY
    hikari:
      connectionTimeout: 30000
      idleTimeout: 600000
      maxLifetime: 1800000
      maximumPoolSize: 10
  jpa:
    hibernate:
      ddl-auto: update
      naming:
        physical-strategy: org.hibernate.boot.model.naming.PhysicalNamingStrategyStandardImpl
        implicit-strategy: org.onap.policy.common.spring.utils.CustomImplicitNamingStrategy
    properties:
      hibernate:
        format_sql: true

spring:
  datasource:
    url: jdbc:h2:mem:testdb
    driverClassName: org.h2.Driver
    hikari:
      maxLifetime: 1800000
      maximumPoolSize: 3
  jpa:
    hibernate:
      ddl-auto: create
    open-in-view: false

• Unit Tests may need some changes
