Description

Together with Update_Suppression_Limit, this parameter forms the throttling for the Update task: if a database reaches the limit within Update_Suppression_Time minutes, further update requests for that DB are ignored for the duration of this window. Only after the time window expires does normal indexing resume. The goal is to keep the server operational during “index stampedes” caused by faulty or hyperactive applications.

Example configuration

Update_Suppression_Limit=100
Update_Suppression_Time=15

Notes & pitfalls

  • Only effective in combination with Update_Suppression_Limit.
  • During the suppression window, views of the affected DB are not current – users notice the delay.
  • Takes effect after a server restart.
  • Regularly check log messages “Update suppressed”.
