SIENTIAPDE-1214: Refactor MLFlow and model repository methods to use model_config dictionary - Updated MLFlow class methods to accept model_config instead of model_retention for improved flexibility. - Modified model_repository methods to handle model_config, extracting necessary parameters for transformation and prediction. - Adjusted predictions_batch and prediction_process workflows to utilize model_config for better configuration management. - Commented out the previous sientia-mlops-library dependency in requirements.txt for clarity.

"""
|
|
Main batch prediction workflow for the Laborious system.
|
|
|
|
This workflow orchestrates the complete batch prediction process, handling
|
|
data loading, configuration management, and workflow delegation. It serves
|
|
as the primary entry point for batch prediction operations and ensures
|
|
proper data preparation before ML model inference.
|
|
|
|
The workflow implements a robust data processing pipeline with:
|
|
- Custom SQL query execution for data loading
|
|
- Comprehensive configuration management
|
|
- Data quality filter application
|
|
- MLFlow model integration
|
|
- Workflow delegation to specialized sub-workflows
|
|
|
|
Workflow Execution:
|
|
1. Data Loading: Executes custom SQL query to load prediction data
|
|
2. Configuration Preparation: Sets up prediction parameters and filters
|
|
3. Workflow Delegation: Spawns PredictionProcess child workflow
|
|
4. Error Handling: Implements comprehensive error handling and retry policies

|
|
Execute the batch prediction workflow.
|
|
|
|
This method orchestrates the complete batch prediction process by:
|
|
1. Loading data using the provided custom SQL query
|
|
2. Preparing prediction configuration and filters
|
|
3. Delegating to the PredictionProcess workflow for ML operations
|
|
|
|
The method implements comprehensive error handling and ensures all
|
|
required parameters are properly configured before proceeding.
|
|
|
|
Args:
|
|
input_data: Complete configuration for the batch prediction
|
|
Required keys:
|
|
- schedule_name (str): Schedule identifier for the prediction
|
|
- model_name (str): Name of the ML model to use
|
|
- model_id (int): Unique identifier for the model
|
|
- query (str): SQL query for data loading
|
|
- schema (dict, optional): Data schema definition
|
|
- table_name (str, optional): Target table for predictions
|
|
- input_filters (dict, optional): Data quality filters
|

- mlflow_transform_filters (dict, optional): MLFlow transform filters
|
|
- mlflow_predict_filters (dict, optional): MLFlow prediction filters
|
|
- model_retention (int, optional): Model retention period in minutes
|
|
- path_priority (list[str]): Decision path priority configuration
|
|
- opc_output_config (dict, optional): OPC server export configuration
|
|
- datetime_columns (list[str], optional): Columns to treat as datetime
|
|
|
|
Returns:
|
|
None: The workflow completes successfully when the child workflow finishes
|
|
|
|
Raises:
|
|
Exception: If any required parameters are missing or if the workflow fails
|
|
during data loading or workflow delegation
