Where Apex is not suitable

On the other hand, there are a few related areas of interest that Apex does not target or is less suited for (as of this writing):

• Data exploration in ad hoc, experimental environments such as Spark's interactive shell.
• Machine learning. Apex currently does not have its own library of machine learning algorithms, although it does have the capability for iterative processing and can be used as execution engine as seen in Apache SAMOA.
• Interactive SQL. Apex has basic support for streaming SQL transformations, but is not comparable to Hive or similar tools.
• At the time of writing, Apex does not have support for Python, although it is being discussed within the community and likely to happen in the future. (The Apex library has a Jython operator, but users typically want to run native Python code and also specify the pipeline in Python.)
