Configure Modeling Task Fields for Data Lineage & O&M - Dataphin - Alibaba Cloud - Dataphin

You can perform O&M operations on fields in modeling tasks, including logical dimension tables, logical fact tables, and logical aggregate tables.

Field and batch operations page access

In the top menu bar of the Dataphin homepage, choose Development > Task O&M.
In the left-side navigation pane, choose Task O&M > Recurring Task.
In the top menu bar, select the production or development environment.
On the Recurring Task page, click the Modelling Task tab.
On the Modelling Task page, click the icon in the Actions column of the target task, select Fields And Batch Operations to access the modeling task field management page.

Field and batch operations page introduction

The Field and batch operations page contains the basic information, search and filter, metric (field) task list, and batch operation areas. Use this page to perform O&M operations on submitted logical table task fields.

The page layout is the same for logical dimension tables, logical fact tables, and logical aggregate tables. The following figure uses a logical aggregate table as an example.

Parameter	Description
①Basic information	Displays basic information about the logical table. Dimension and fact logical tables: Include logical table type, logical table name, O&M owner, last update time, and project. Logical aggregate table: Include logical table type, logical table name, and last update time.
②Search and filter	Search: Search by field name or metric description (field description). Filter: For logical aggregate tables, filter metrics (fields) by O&M owner, project, and scheduling cycle.
③Metric list (field list)	Lists the metrics (fields) in the logical table. Dimension/fact logical tables: Include field name, field description, and field type. Supported operations include data backfill, view production lineage, and view consumption lineage. Logical aggregate tables: Include metric name, metric description, scheduling cycle, last update time, O&M owner, project, and field type. Supported operations include single field data backfill, data backfill, modify O&M owner, view production lineage, and view consumption lineage. Logical tables support the following operations: Single field data backfill: Available for metrics in logical aggregate tables. Configure the following parameters for single field data backfill. Instance name: Auto-generated in the format `Custom (logical table name)_field English name_logical table model ID_run date_timestamp`. You can modify the Custom part. Data timestamp: Specify the data timestamp range for the backfill. Concurrent running groups: Controls how many data backfill processes run simultaneously. The default value is 1. Valid values: integers between 1 and 12. Important In single field data backfill mode, Dataphin does not automatically identify or select related fields based on data consistency or the same materialization node principle. This may affect the correctness of output data. Data backfill: Refreshes data for fields (metrics) within specified historical data timestamps. For more information, see Appendix: Recurring task data backfill. Modify O&M owner: Change the O&M owner of a metric in a logical aggregate table. View production lineage: View the production lineage of a single logical table field. If a field is stored in multiple materialization nodes, use the Select Production Lineage dropdown list to switch between lineages. You can also click a logical table task node to view node information. Click View Node Details to view node details, operation logs, and node code. View consumption lineage: View downstream dependencies of a single logical table field to analyze the impact on descendant nodes. You can also click a descendant node to view node information such as Task overview, Operation log, and Node code. The available information varies by node type.
④Batch operations	For logical aggregate tables, batch-modify the O&M owner of selected metrics.
