Publication repository

Publication repository

Cloud Integration Hub
stores topic data in a publication repository, in a structure that represents the structure in which you want to keep the data.
The publication repository stores the data for a short intermediate period after the data is consumed by all subscribers.
Cloud Integration Hub
stores the data in the publication repository in the following ways:
  • For each publication instance, the retention period for consumed data starts if all the subscribers have either successfully consumed or discarded the data. That is, after all the events that are associated with the publication instance are either in a Complete or in a Discarded event status. If all the subscribers consume or discard the data,
    Cloud Integration Hub
    stores the consumed data in the publication repository until the retention period for consumed data expires, and then deletes the consumed data from the publication repository.
  • Cloud Integration Hub
    stores unconsumed data in the publication repository until the retention period for unconsumed data expires, and then deletes the unconsumed data from the publication repository.
You can use a hosted publication repository or a private repository.
Hosted publication repository
Cloud Integration Hub
hosts and manages the publication repository on
Informatica Intelligent Cloud Services
Hosting Services. Storage usage of the repository shows on the
Cloud Integration Hub
home page.
Private publication repository
Use your own, private repository. A private publication repository can reside on-premises or on the organization's private cloud and must reside on an Oracle, Microsoft SQL Server, or MySQL database. The repository must be accessible through the
Informatica Intelligent Cloud Services
Secure Agent. It is recommended that the Secure Agent and the private repository reside in the same location.
When you use a private publication repository, note the following requirements:
  • The organization must have a valid
    CIHProcessor
    license in
    Informatica Intelligent Cloud Services
    . To activate the license, Contact Informatica Global Customer Support.
  • To ensure the stability and ongoing functionality of
    Cloud Integration Hub
    , don't make any changes to the repository. For example, don't modify topic tables or modify data files in the repository.
