* [Improved query performance with direct field population in CI tables](https://www.servicenow.com/docs/dikZ2lIS1bNpgxWtTOukSQ "The Populate Service Account and LDC IN CMDB scheduled job populates the Service Account and Logical Datacenter fields in cloud configuration item (CI) tables, and the Virtual Machine Object field in the Hardware [cmdb_ci_hardware] table. This direct population reduces query complexity and improves query performance.")
* [Available cloud discovery patterns](https://www.servicenow.com/docs/5jEn4sISqxcs1FRdlB5hQQ "ITOM Visibility comes with an extensive library of patterns that can discover your cloud environment: AWS, Azure, GCP, IBM, and OCI.")  
**Related tasks**   

* [Set the Populate Service Account and LDC job stale threshold](https://www.servicenow.com/docs/qvlcPBjeMolHuCihikoHdQ "Configure the number of days before a running Populate Service Account and LDC IN CMDB job is considered stale and canceled. Increase this value if a large configuration item (CI) dataset causes the job to be canceled before a full run completes.")
* [Trigger a full CI table resync for direct field population](https://www.servicenow.com/docs/ASZdoniulyuqYfWY_txMpQ "Trigger the Populate Service Account and LDC IN CMDB scheduled job to reprocess all configuration item (CI) records.
