Lineage harvester system requirements

You need to meet the system requirements to be able to install and run the lineage harvester.

Software requirements

Java Runtime Environment version 11 or newer, or OpenJDK 11 or newer.

For Java Runtime Environment 16 or newer, or OpenJDK 16 or newer, set the JAVA_OPTS environment variable for the lineage harvester to function properly:

JAVA_OPTS='--illegal-access=deny'

Note To ingest Snowflake data sources, the minimum requirement is Java Runtime Environment version 16 or newer, or OpenJDK 16 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 Technical lineage general troubleshooting.
  • 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 the lineage harvester configuration file.
    • All Collibra Data Lineage service instances in your geographic location:
      • 15.222.200.199 (techlin-aws-ca.collibra.com)
      • 18.198.89.106 (techlin-aws-eu.collibra.com)
      • 54.242.194.190 (techlin-aws-us.collibra.com)
      • 51.105.241.132 (techlin-azure-eu.collibra.com)
      • 20.102.44.39 (techlin-azure-us.collibra.com)
      • 35.197.182.41 (techlin-gcp-au.collibra.com)
      • 34.152.20.240 (techlin-gcp-ca.collibra.com)
      • 35.205.146.124 (techlin-gcp-eu.collibra.com)
      • 34.87.122.60 (techlin-gcp-sg.collibra.com)
      • 35.234.130.150 (techlin-gcp-uk.collibra.com)
      • 34.73.33.120 (techlin-gcp-us.collibra.com)

      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. In addition, we highly recommend that you always allow the techlin-aws-us instance as a backup, in case the lineage harvester cannot connect to other Collibra Data Lineage service instances.
