To configure initial tuning, set the number of times that CLAIRE runs the

mapping

task, with

10

being the minimum. Click

Tune

to begin tuning. When tuning begins,

Data Integration

creates a tuning job with multiple subtasks to represent each run of the

mapping

task. You must wait for all subtasks to complete before you can view the tuning results.

Each time that CLAIRE runs the

mapping

task, CLAIRE gathers task performance data to improve its recommendation for an optimal set of Spark properties.
