# 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: 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.
