  1. According to Kafka Docs,

From a security perspective, we recommend you use the latest released version of JDK 1.8 as older freely available versions have disclosed security vulnerabilities. LinkedIn is currently running JDK 1.8 u5 (looking to upgrade to a newer version) with the G1 collector.


  1. Hardware and OS requirements:

You need sufficient memory to buffer active readers and writers. You can do a back-of-the-envelope estimate of memory needs by assuming you want to be able to buffer for 30 seconds and compute your memory need as write_throughput*30.

The disk throughput is important. We have 8x7200 rpm SATA drives. In general disk throughput is the performance bottleneck, and more disks is better. Depending on how you configure flush behavior you may or may not benefit from more expensive disks (if you force flush often then higher RPM SAS drives may be better).


Kafka should run well on any unix system and has been tested on Linux and Solaris. We have seen a few issues running on Windows and Windows is not currently a well supported platform though we would be happy to change that.


  1. OpenJDK is a free and open-source implementation of the Java SE Platform Edition. There are no major technical differences between OpenJDK and OracleJDK however, you should note that Oracle will deliver releases every 3 years with long term support, while OpenJDK will be released every six months and will only support the newest release available.

  1. Yes
  2. https://docs.oracle.com/javase/8/docs/technotes/guides/install/windows_system_requirements.html should indicate similar requirements to the current version of openjdk.
  3. OpenJDK is an open source version of the JDK. Oracle's JDK is not open source and requires a license for non personal use. There isn't any large technical difference between the two. Oracle's JDK builds from OpenJDK.
