Service Graph Connector For AWS - Cloud OS Image modelCurrently AWS connector is using [cmdb_ci_os_template] table to store Cloud OS Images, this may end up in unusually large number of records. This behaviour is caused by dependency on other classes, it cause each dependency to have one to one connection. To avoid this issue, OS images can now be stored in the Cloud Image [cmdb_ci_cloud_os_image] table. The new Image model creates one record for each public Image (object id) irrespective of the service account and populates them in the Cloud Image [cmdb_ci_cloud_os_image] table. Therefor, the new model reduces the number of records in the CMDB Before migrating to the new image model, we need to delete all the data from older model To Delete old model OS image records, import the update set in Global Scope and commit it. Once the update set has been committed, follow the steps below: Navigate from the Filter Navigator -> System Definition -> Scheduled Jobs -> Search for job Named "SG-AWS - Mark old image records as Absent"Activate the Scheduled job by clicking on "Active" and then click on "Update"This Schedule Job will periodically update the old model(cmdb_ci_os_template) CIs status as Absent. Table cleaner will clean the Absent records in cmdb_ci_os_template table.This schedule Job deletes all the records from the cmdb_ci_os_template table which populated by "SG-AWS", expect this step to take time(maybe days depending on Ci's in cmdb_ci_os_template table). Once all the required records are deleted from older model, to migrate to a new image model, set the System Property "sn_cmdb_ci_class.use_single_cloud_os_image" to true. To do this, Navigate to Filter Navigator -> enter sys_properties.list -> Search for sn_cmdb_ci_class.use_single_cloud_os_image Note: 1. If you haven't deleted old model hardware type records but migrated to a new model and run SGC AWS, you may observe both old and new image records and relations in CMDB. 2. You can adjust the repeat interval of job and can also create below system property value to optimize the performance. delete_old_image_batch_size - The number of records updated during each Job process. The default value is 10000
