Long running processes; caching config or clients -- considerations

[marc-ostrow]

I did not notice recommendations on caching and reuse of a built configuration, nor instantiated service clients, especially in the context of a long running application https://aws.github.io/aws-sdk-go-v2/docs/configuring-sdk/

• Are there any negative consequences of reusing the same configuration during a long running process? Given EC2, I suppose a long running process could get bitten if the IAM Role was replaced on the running EC2, for example. However, there is an ec2rolecreds credentials provider. If the configuration was configured with this credentials provider, this wouldn't be an issue, presumably.

• Are there any negative consequences of reusing the same instantiated service client? Would errors on the client be reason enough to create a new client?

Thanks in advance.
