The short version

  • Each has a real cost: Oracle Database high licensing costs for Enterprise Edition with option packs potentially doubling the effective per-processor cost; Apache Spark MLlib apache Spark MLlib is Apache 2.0 licensed and free with no paid tier from the Apache project itself; SLA-backed support has to be sourced from a third party such as a managed Spark vendor rather than from Apache.
  • They diverge on capability: Oracle Database covers PL/SQL, Apache Spark MLlib covers Classification.
