To optimize your campaign performances in Talend Data Stewardship, you need to, at least, make sure the number of tasks in the campaign does not exceed 100,000.

The performances of a campaign can be impacted by various elements. When a campaign contains more than 100,000 tasks, a warning is displayed next to a campaign name in the Campaigns tab or in the Tasks tab. The Campaign Owner needs to, at least, reduce the number of tasks in the campaign below this threshold to remove the warning message.

Besides, here are some elements to take into consideration to improve the performances of the campaign:
  • The number of tasks
  • The number of attributes in the data model: Talend recommends not to exceed 50 attributes
  • The campaign type
  • The number of task sources in a Grouping or Merging campaign
  • The number and type of constraints
  • The number of rules
  • The number of campaigns depending on the same data model
Tip: A good practice is to delete unused campaigns.
