Cached data

Sometimes, you may wish to resolve many resources (semi-) simultaneously, which may degrade upstream response times. In these cases, follow these steps:

  1. Upload the data set (csv format, see model .../channelregistrycache/db/model/ChannelRegistryCacheDao.java) to the s3 bucket channel-register-cache-{accountId}
  2. If channel registry data already exists in dynamoDB, empty the table channel-register-cache-{stackName}
  3. Trigger LoadCacheButtonHandler lambda function
  4. Configure the ApplicationConfigurationProfile:
    • Navigate to AWS Systems Manager → AppConfig.
    • Choose ApplicationConfig → ApplicationConfigurationProfile.
    • If there is no existing version with the value you want to deploy → navigate to Systems Manager, Parameter Store and update the SSM parameter named ApplicationConfigurationParameter. Update publicationChannelCacheEnabled value to true or false.
    • Return to ApplicationConfig → ApplicationConfigurationProfile and choose version of Config you want to deploy.
    • During deployment, select the environment you want to use. Currently, there is a single environment named Live. Choose the deployment strategy AllAtOnce.
    • Press Start deployment.
    • Please note that deployment may take some time.

!Important: Caching is only supported for fetching publication channels by id and year, not search.
