Parameter

Description

Parameters Setting

Business base date

You can set this parameter in one of the following ways:

• Enter the date directly. Example: 20230210.

• Reference global variables. For more information, see Advanced feature: global variable.

Whether to open multi-date loop execution

Multi-date loop execution is enabled by default. If multi-date loop execution is disabled, this component functions the same as the MR component.

Execution time window

The value can contain integers and time ranges. Separate time ranges with commas (,).

The system calculates the execution time based on the Business base date and starts subtasks at the specified time. Up to 100 subtasks can be executed.

For example, if you set the Business base date to 20230210 and the Execution time window to (-4,-2],0, then tasks are executed on data obtained for 20230207, 20230208, and 20230210.

Maximum number of concurrent

We recommend that you do not run a large number of concurrent tasks at a time to avoid resource contention. Default value: 3.

Date format

The value is used to generate the ${pai.system.cycledate} system variable. Valid values:

• yyyyMMdd: this is the default value.

• yyyy-MM-dd

• yyyy/MM/dd

Example: If you set the Business base date to 20230210 and the Date format to yyyy-MM-dd, then the ${pai.system.cycledate} variable in the SQL script is converted to 2023-02-10.

Resource OSS Path

The directory where the resource file is located.

List of resource files

Separate multiple resource files with commas (,).

OSS path of classpath

The path of the JAR file.

Main class

MR task input parameters

If the multi-date loop execution is enabled, you need to replace the date with the system variable ${pai.system.cycledate}.

As is set in the example of this topic, three tasks are started in parallel. Other features are the same with the MR component.
