Resource-level throttling - Amazon GameLift Servers
Services or capabilities described in Amazon Web Services documentation might vary by Region. To see the differences applicable to the China Regions, see Getting Started with Amazon Web Services in China (PDF).

Resource-level throttling

Some API operations are subject to resource-level throttling to prevent database hot key issues. While increasing API-level limits for these operations, they may still be throttled at the resource level.

The following API operations are subject to resource-level throttling:

  • DescribeGameSessionPlacement

  • DescribeGameSessions

  • DescribeMatchmaking

  • DescribePlayerSessions

Resource-level throttling is enforced using specific throttle keys that include resource identifiers. For example, DescribeGameSessionPlacement uses the key "Operation:GameLift/DescribeGameSessionPlacement,aws-account-placement-id:" which enforces throttling per account and placement ID combination. This prevents customers from overwhelming the system with requests for specific resources.
