CachableSecretsManager (AWS Athena Query Federation 2022.47.1 API)

java.lang.Object
- com.amazonaws.athena.connector.lambda.security.CachableSecretsManager

```
public class CachableSecretsManager
extends Object
```
Since Athena may call your connector or UDF at a high TPS or concurrency you may want to have a short lived cache in front of SecretsManager to avoid bottlenecking on SecretsManager. This class offers such a cache. This class also has utilities for idetifying and replacing secrets in scripts. For example: MyString${WithSecret} would have ${WithSecret} replaced by the corresponding value of the secret in AWS Secrets Manager with that name.
