System Requirements
Hardware
The following machine recommendations are for installing individual PADAS components:
| Component | Storage | Memory | CPU | Nodes |
|---|---|---|---|---|
| Engine | SSD storage is recommended. Disk size depends on the number of transformations and queries. For evaluation/test/dev 10-20GB should be sufficient. | 12GB (64GB recommended) | 4 CPU cores or more | 1 to many instances can be deployed depending on number of Kafka topic partition count and scalability requirements |
| User Interface | 50GB, preferably SSD | 2GB | 1 CPU core or more | 1 |
Software
PADAS requires a running Kafka platform (e.g. Apache Kafka or Confluent Platform in order to operate properly. Namely, the following Kafka components must be running:
- Kafka Controller (or Zookeeper)
- Kafka Broker

Java
Java 17 is the recommended version in this version of Padas. Java 11 and later versions are also supported. From a security perspective, we recommend the latest released patch version as older freely available versions may have disclosed security vulnerabilities.
For more information regarding Confluent Platform, please visit here.
NOTE: You need to separately install the correct version of Java before you start the installation process.
JVM Heap Options can be set via PADAS_HEAP_OPTS environment variable. Default value is: -Xmx1G -Xms1G
NOTE: When using systemctl to start the service, you'll need to edit padas.service file to make a change in JVM heap options.
