Lineage harvester system requirements

Warning The CLI lineage harvester is now deprecated and will officially reach its end-of-life on July 31, 2026. To ensure a smooth transition, we encourage you to begin creating technical lineage via Edge, if you haven't already.

To install and run the lineage harvester, you have to meet the following requirements.

Software requirements

Java Runtime Environment version (JRE) 17 or newer, or OpenJDK 17 or newer.

Hardware requirements

You need to meet the hardware requirements to install and run the lineage harvester.

Minimum hardware requirements

You need the following minimum hardware requirements:

2 GB RAM
1 GB free disk space

Recommended hardware requirements

The minimum requirements are most likely insufficient for production environments. We recommend the following hardware requirements:

4 GB RAM
Tip 4 GB RAM is sufficient in most cases, but more memory could be needed for larger harvesting tasks. For instructions on how to increase the maximum heap size, see the advice on how to resolve Java heap space errors, in the Collibra Support Portal.
20 GB free disk space

Network requirements

The lineage harvester uses the HTTPS protocol by default and uses port 443.

You need the following minimum network requirements:

Firewall rules so that the lineage harvester can connect to:

The host names of all data sources in your lineage harvester configuration file.

All Collibra Data Lineage service instances in your geographic location:

Region	DNS name
aws-ca	techlin-ca-central-1.collibra.com
aws-eu	techlin-eu-central-1.collibra.com
aws-me	techlin-me-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

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.

Note

The lineage harvester connects to different Collibra Data Lineage service instances based on your geographic location and cloud provider. If your location or cloud provider changes, the lineage harvester rescans all your data sources.

You have to allow all Collibra Data Lineage service instances in your geographic location.
Regardless of your geographic location, you have to allow one of the following. This is required to retrieve the API Key. No other data is transferred.

Region	DNS name
aws-ca	techlin-ca-central-1.collibra.com
aws-eu	techlin-eu-central-1.collibra.com
aws-us	techlin-us-east-1.collibra.com
gcp-us	techlin-us-east1.collibra.com

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.

Region	DNS name
aws-us	techlin-us-east-1.collibra.com
