Dataphin:Configure real-time template running parameters

Procedure

1. Navigate to the Dataphin home page, and single click on the top menu bar Development > Data Development.

2. On the Data Development page, use the operation guide shown in the figure below to select the desired real-time template, manage historical versions, and access the template version management page.

   

3. In the Configuration dialog box, set the running parameters.

   Default running parameters for real-time templates:

   Flink real-time computing engine

   execution.checkpointing.interval: '180s'
   execution.checkpointing.min-pause: '180s'
   table.exec.state.ttl: 36 h

   Ververica Flink real-time computing engine

   execution.checkpointing.externalized-checkpoint-retention: RETAIN_ON_CANCELLATION
   metrics.reporters: promappmgr
   metrics.reporter.promappmgr.port: '9999'
   metrics.reporter.promappmgr.class: org.apache.flink.metrics.prometheus.PrometheusReporter
   dataphin.vvp.v2: true
   execution.checkpointing.interval: '180s'
   execution.checkpointing.min-pause: '180s'
   table.exec.state.ttl: 36 h

   Running parameter merge and precedence:

   • By default, tasks derived from the template adopt the template's running configuration.

   • For a new job, the parameters combine: Default Task Running Parameters + Project Task Running Parameters.

   • For a new template, the parameters combine: Default Task Running Parameters + Project Task Running Parameters.

   • If the default and project running parameters share a common parameter, the project parameter value takes precedence.

   • A new template task uses the template's running parameters. If the template parameters are unchanged, the task parameters match those of non-template tasks. Any changes to the template parameters apply to the new task.

   • When you modify template parameters, existing parameter values in template tasks remain unchanged, and new parameters are added.

4. To finalize the configuration of running parameters, single click OK.
