What Are the Impacts of ServiceComb Engine API Call Failures on Services?

Prerequisite

Microservices use the Spring Cloud Huawei or Java chassis framework.

Will Services Be Affected If the Registration Center API Fails to Be Called to Obtain Microservice Information?

  • If the Spring Cloud Huawei framework version is 1.11.12-2024.0.x, 1.11.12-2023.0.x, 1.11.12-2021.0.x, or later, or the Java chassis framework version is 2.8.27 or later, API call failures will not cause local cache to be cleared. Therefore, services are not affected.
  • If the Spring Cloud Huawei or Java chassis framework version is earlier than the preceding versions, API call failures will cause local cache to be cleared. Therefore, services are affected. In this case, upgrade the framework version.

Will Services Be Affected If the Configuration Center API Fails to Be Called?

  • If a microservice fails to call the configuration center API during startup, the service startup may be affected.
  • If a microservice fails to call the configuration center API during running, only the configuration cached locally can be obtained. The latest configuration can be obtained only when the API is successfully called.
