Requirements¤
This page lists software and hardware requirements for eccenca Corporate Memory deployments. For a general overview of a deployment setup please refer to the System Architecture.
Minimal Setup¤
A minimal single-node deployment for testing/evaluation purposes means:
- no memory consuming linking and transformation workflows,
- nearly no concurrent users.
Depending on how much RAM is dedicated to the triple store, Knowledge Graphs up to several million triples can be built and served.
- Operating System / Hardware
- Bare metal server or VM with Debian based linux OS (see Installation for details)
- 16 GB RAM
- 100 GB free disk space (10 GB for docker images + data + logs over time)
- docker and docker compose (we deliver an orchestration including all needed components)
For an example of a single-node installation refer to the following scenarios:
Typical Setup¤
In a typical deployment all components are installed in a kubernetes cluster.
The following numbers are based on existing customer deployments running Knowledge Graphs up to 300 million triples.
| Component | CPU | Memory |
|---|---|---|
| eccenca Explore | >= 2 cores1 | >= 4 GB RAM |
| eccenca Build (DataIntegration) | >= 4 cores2 | >= 8 GB RAM2 |
| Triple / Quad Store | >= 8 cores1 | >= 16 GB RAM3 |
| Keycloak incl. PostgreSQL4 | 2 cores | >= 2 GB RAM |
For GraphDB always also have a look at GraphDB recommendations.
