Postgres failover

Google Cloud Apigee
1

Hello,

On this page, the postgres failover procedure is described.
https://docs.apigee.com/private-cloud/v4.17.05/handling-postgressql-database-failover

My question is: what do I need to do with the other components, when performing this failover?

  • Is the API functionality still working? (postgres only handles storing the analytics part for API calls?)

  • do I need to stop Qpid?

  • do I need to stop any other components?

Thanks,

Joris

Hi,

If the PostgreSQL is down yes API calls will work perfectly fine because other components are up such as RMP’s ,QPID etc.

QPID is having QUE mechanism which stores the API requests in QUE and wait for the Postgres DB to be up.

You don’t need to stop any other component expect Postgres Itself , for making slave as master as described in this link “https://docs.apigee.com/private-cloud/v4.17.05/handling-postgressql-database-failover”.

Thanks,

Haider
