Connection Pool

When updating a traffic policy, you can determine whether to enable connection pool management.

Connections and requests that exceed the thresholds are cut off to protect target services.

Connection pool management allows you to configure thresholds. In this way, the failure of a service will not cascade and affect the entire application. Connection pool settings are applied to each upstream service instance over either TCP or HTTP.

Connection pool management allows you to control the requests from service1 to service2 as follows:

  1. If the number of requests does not exceed the configured maximum number of connections, the requests will be allowed.
  2. If the number of requests does not exceed the maximum number of pending requests, the requests will enter the connection pool.
  3. If the number of requests exceeds the maximum number of pending requests, the requests will be denied.
