    Description

      Analytics tables and files needs a cleanup process like everything in software, we need to define what and when.

      What, must be cleaned:

      • Unexisting contexts predictions
      • Unexisting predictions actions (MDL-58835) both when the prediction context does not exist and when the model is deleted
      • Deleted models logs (we already delete all other model data)
      • Deleted models files (all analysable files + merged files)
      • Calculations belonging to contexts that do not exist anymore (analytics_indicator_calc)

      What we can discuss if it should be cleaned or not:

      • Deleted analysable records (analytics_predict_samples, analytics_train_samples) once the analysable is not available anymore
      • Deleted analysable files (evaluation and prediction files) once the analysable is not available anymore

      What I would vote to keep:

      • Deleted analysables training files
