The Collibra Data Lineage service processes and analyzes the harvested metadata from supported (meta)data sources and uploads it to Data Catalog. The Collibra Data Lineage service processes or stores only metadata, but not actual data.
When you run the lineage harvester or synchronize the technical lineage on Edge, the lineage harvester or technical lineage via Edge firstly connects to any available Collibra Data Lineage service instance to determine your cloud provider and geographic location of your Collibra Data Intelligence Platform environment. Then, the lineage harvester or technical lineage via Edge sends the harvested metadata to the Collibra Data Lineage service instance with the same cloud provider and geographic location.
Currently, your metadata can be processed on one of the following Collibra Data Lineage service instances:
| Region | DNS name |
|---|---|
| aws-ca | techlin-ca-central-1.collibra.com |
| aws-eu | techlin-eu-central-1.collibra.com |
| aws-sg | techlin-ap-southeast-1.collibra.com |
| aws-us | techlin-us-east-1.collibra.com |
| gcp-au | techlin-australia-southeast1.collibra.com |
| gcp-ca | techlin-northamerica-northeast1.collibra.com |
| gcp-eu | techlin-europe-west1.collibra.com |
| gcp-sg | techlin-asia-southeast1.collibra.com |
| gcp-uk | techlin-europe-west2.collibra.com |
| gcp-us | techlin-us-east1.collibra.com |
Note We recommend that you only use DNS names in your network configurations, as the IP addresses are subject to change periodically. If you need to use IP addresses in your network configuration, we recommend using a command line utility like nslookup to query the DNS and obtain the mapping between domain name and IP address.
Important You have to allow all Collibra Data Lineage service instances in your geographic location. For example, if your data is located in Europe, you have to allow the following Collibra Data Lineage service instances: "techlin-eu-central-1" and "techlin-europe-west1". In addition, we highly recommend that you always allow the "techlin-us-east-1" instance as a backup, for license verification, in case the lineage harvester cannot connect to other Collibra Data Lineage service instances.
