| ## Prompt |
| **Task Objective**: From the hot table governance metadata detail table, filter valid hot table records (heat > 0, excluding temporary/test tables), aggregate by database name and table name to take the maximum of each metric, and write the results to the output table. |
|
|
| **Input Table**: |
| - `internal_platform_db.ads_gov_cost_table_govern_detail_df_prestosql_005` (hot table governance metadata detail table) |
| - `imp_date` BIGINT — date partition |
| - `db_name` STRING — database name |
| - `table_name` STRING — table name |
| - `heat` BIGINT — heat |
| - `owner` STRING — owner |
| - `storage_detail` DOUBLE — storage detail |
| - `task_cnt` BIGINT — task count |
| - `table_type` STRING — table type |
| - `govern_status` STRING — governance status |
| - `last_access_time` STRING — last access time |
| - `table_comment` STRING — table comment |
| - `partition_cnt` BIGINT — partition count |
| - `file_format` STRING — file format |
| - `table_size` DOUBLE — table size |
| - `avg_file_size` DOUBLE — average file size |
| - `is_partitioned` INT — whether partitioned |
| - `lifecycle_days` INT — lifecycle days |
| - `create_time` STRING — creation time |
| - `modify_time` STRING — modification time |
| - `project_name` STRING — project name |
|
|
| **Filter Conditions**: |
| - `imp_date = 20260507` |
| - `heat > 0` |
| - `table_name NOT LIKE '%temp%'` |
| - `db_name NOT LIKE '%test%'` |
|
|
| **Output Requirements**: |
| - Target table: `internal_platform_db.dwd_hot_metadata_table_cand_prestosql_005` |
| - Output fields and order: `dt` STRING, `db_name` STRING, `table_name` STRING, `owner` STRING, `storage_detail` DOUBLE, `heat` BIGINT, `task_cnt` BIGINT, `table_type` STRING, `govern_status` STRING, `last_access_time` STRING, `table_comment` STRING, `partition_cnt` BIGINT, `file_format` STRING, `table_size` DOUBLE, `avg_file_size` DOUBLE, `is_partitioned` INT, `lifecycle_days` INT, `create_time` STRING, `modify_time` STRING, `project_name` STRING |
| - `dt`: Fixed value `'20260507'` |
| - Group by `db_name`, `table_name`, apply `MAX()` to all other fields |
| - If the target table does not exist, first create the table, then write the data |
| - Use Presto/Trino SQL syntax; do not use Hive/Spark SQL dialects |
|
|
| **Environment and Execution Notes**: |
| - Presto is running, connected via the Hive catalog |
| - Execute SQL: `presto-cli --catalog hive --schema internal_platform_db -f /tmp_workspace/result.sql` |
| - After writing `result.sql`, you must execute it yourself to verify that it runs successfully and produces correct data |
