Prompt

Task Objective: Summarize the current day's actual and estimated benefit metrics for low-value tasks, grouped by planning product, operations product, OBS product, and application group dimensions.

Business Background and Objective: Low-value task governance requires summarizing the current day's actual benefits (task count, runtime, CPU, memory) and estimated benefits (task count, runtime, CPU, memory) at the application group level to evaluate governance effectiveness. This task groups the detail data from the specified partition of the input table by four dimension fields, applies SUM aggregation to all metric fields, and writes the results to the output table.

Input Table (full name + brief description):

• internal_platform_db.dws_low_value_task_compute_statistics_day_mysql_011 (low-value task compute benefit detail daily table)

(Please connect to the database and query to confirm the table structure and field semantics.)

Processing Rules:

• No joins, single-table processing
• Filter condition: dt = '20260507'
• Aggregation logic: Group by plan_product_name, obs_product_name, product_name, dw_appgroup, applying SUM to all metric fields (actural_task_count, actural_time_sum_hour, actural_vcore_sum_vcore_hour, actural_memory_sum_gb_hour, estimated_task_count, estimated_time_sum_hour, estimated_vcore_sum_vcore_hour, estimated_memory_sum_gb_hour)

Output Requirements:

• Target table: internal_platform_db.dws_low_value_task_compute_appgroup_stats_day_cand_mysql_011
• Output field order: dt, plan_product_name, obs_product_name, product_name, dw_appgroup, actural_task_count, actural_time_sum_hour, actural_vcore_sum_vcore_hour, actural_memory_sum_gb_hour, estimated_task_count, estimated_time_sum_hour, estimated_vcore_sum_vcore_hour, estimated_memory_sum_gb_hour
• dt field value: '20260507'
• Types: dt VARCHAR(8), plan_product_name VARCHAR(256), obs_product_name VARCHAR(256), product_name VARCHAR(256), dw_appgroup VARCHAR(256), actural_task_count INT, actural_time_sum_hour DOUBLE, actural_vcore_sum_vcore_hour DOUBLE, actural_memory_sum_gb_hour DOUBLE, estimated_task_count INT, estimated_time_sum_hour DOUBLE, estimated_vcore_sum_vcore_hour DOUBLE, estimated_memory_sum_gb_hour DOUBLE
• If the target table does not exist, first create it using standard MySQL InnoDB format, then write the data
• Use standard MySQL syntax; do not use Hive/Spark SQL dialects (e.g., INSERT OVERWRITE, STORED AS ORC, PARTITIONED BY are not supported)
• Write method: Use INSERT INTO ... SELECT ... statements

Environment and Execution Notes:

• Your final output must be written to the file /tmp_workspace/result.py, not result.sql
• The local MySQL is running at localhost:3306, username root, password root123
• Use Python pymysql in result.py to execute the SQL (do not use the mysql command-line tool)
• The script must include complete table creation (if the target table does not exist) and data writing logic
• After writing result.py, you must execute python3 /tmp_workspace/result.py yourself to verify that it runs successfully and produces correct data
