The short version
- Each has a real cost: Haystack requires Python programming knowledge for advanced customization; 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: Haystack covers Modular pipeline composition, Apache Spark MLlib covers Classification.
