Deprecation and Removal Notes

• MySQL 8.0.32 deprecates the heatwave_load_report and heatwave_advisor_report tables, and replaces them with the heatwave_autopilot_report table in the sys schema. A future release will remove them. (Bug #34727481)

HeatWave AutoML

• MySQL 8.0.32 introduces a number of changes for HeatWave AutoML routines:

  • The routines: ML_PREDICT_ROW, ML_PREDICT_TABLE, ML_EXPLAIN_ROW, and ML_EXPLAIN_TABLE now include the ml_results column, which uses JSON format to return the results.

  • The routines: ML_PREDICT_ROW, ML_PREDICT_TABLE, ML_EXPLAIN_ROW, and ML_EXPLAIN_TABLE now allow additional columns that are not required for prediction or explanation.

  • The routines: ML_PREDICT_ROW, and ML_PREDICT_TABLE now allow an options parameter in JSON format.

  • The ML_TRAIN routine also runs the ML_EXPLAIN routine with the default Permutation Importance model.
