Define a throttle for a workload when you create or edit a workload in the Workloads view. When you set a throttle for a workload, any query that is classified into this workload is subject to the throttle you create. You can set state-specific concurrency limits for workload throttles to override the default concurrency limit for a state.
  1. Edit or create a ruleset.
  2. From the ruleset toolbar, click Workloads.
  3. Select or create a workload.
  4. Click the Throttles tab.
  5. Under Default Settings, do one of the following:
    Concurrency Limit Description
    Unlimited Under Concurrency Limit, select Unlimited.
    Limited Under Concurrency Limit , enter a concurrency limit number in the box, and select either Delay or Reject.
  6. [Optional] To override the default settings for a state, do the following:
    1. Next to a state name, click .
    2. Select Create State Specific Settings.
    3. If you do not want to limit the concurrent queries for this state, select Unlimited under Concurrency Limit.
    4. If you want to limit the concurrent queries for this state, enter a concurrency limit number in the box, and select either Delay or Reject.
    5. Click OK.
  7. [Optional] If you have Teradata Database 14.10 with group throttles defined, select a group throttle from the list to change the group throttle membership.
    • This workload must have a delay throttle defined.
    • This workload cannot have a reject throttle defined.
    • This workload can belong to only one group throttle.
    Throttle limits appear for the group throttle and for each workload that is a member of the group throttle.
  8. Click Save.
