# Requirements

### Minimum System Requirements

### Components

#### Streambased Enterprise

* **Nodes**: minimum 3 suggested for resilience, scale horizontally according to workload
* **Storage**: Suggested minimum 100GB SSD
* **Memory**: 16GB
* **CPU**: 4 cores

### Kafka Requirements

* Streambased requires an underlying Kafka cluster of version 2.5.0 or higher.
* For Secure Kafka users, Streambased two roles:
  * **Indexer Kafka User**: Requires read access to all topics that are to be queried (suggested read access to all topics in the cluster).
  * **Server Kafka User**: Requires only topic listing permissions. It is recommended to provide this user with minimum permissions and use impersonation to determine query permissions. Impersonation in Streambased is handled at a per-session level. See the [streambased\_connection](broken://pages/GZu1jqpQYcPPO1pyCA4I) session variable.

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.streambased.io/~/revisions/Yy0ZJ6T3xzCthV9hwnEV/deploy-and-operate/streambased-platform/kafka-service-for-iceberg-k.s.i./requirements.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
