System Overload¶

There could be multiple indications that a system is overloaded:

• Timeouts

• Requests shed - Requests are shed (dropped) when the system cannot process requests fast enough.

• CPU at 100% when no background process (like compaction or repair) runs.

• Queues are getting filled.

If you ruled out data-model problems and hardware failure, this could indicate you need to scale the system.
