-
Added the
xpack.ml.max_model_memory_limit
setting, which can be dynamically updated. For more information, see Machine Learning Settings. -
Added checks and error messages for the
ml.enabled
andml.max_open_jobs
node attributes. These are reserved for internal use and their values should be set by usingxpack.ml.enabled
andxpack.ml.max_open_jobs
machine learning settings.
