System Operator Library

The system operator library contains the platform’s built-in processing operators for selecting operator types and versions in workflow nodes. It is located in the system catalog in Catalog and is read-only.

Dataset Generation

Generate datasets

Open an operator’s details in Catalog / system catalog to view its type, current version, creation and update information, description, input / parameter / output definitions, and version history (version number, date, and change description; the current version is highlighted).

Versions and Workflows

  • A workflow node can be pinned to an operator version. When the platform upgrades a system operator, the behavior of workflows bound to an existing version remains unchanged.

  • To use new behavior, explicitly switch the version on the node and perform regression testing.

  • After an operator is imported to the agent side through a snapshot, it can appear as a tool. See the Glossary for the concept.

Custom Operators (Boundary)

The system library cannot be modified. Place business-specific operators in a regular Catalog directory:

Method

Description

Save from a workflow

Convert a code node, such as SQL or Python, into an operator and specify its directory and database

Write directly in Catalog

Create an operator in a database and maintain its metadata

Common custom-operator metadata includes identifier (English), language (Python / SQL / Go, and others), description, parameter signature (name / type / required / default), and version history. A custom operator can be published as an API or used as an agent tool (see Guide · Catalog / Data Processing for instructions).
