-------------------------------------
Summary: Add per-secret TTL cache to
ParameterProviderSecretsManager
Key: NIFI-15791
URL: https://issues.apache.org/jira/browse/NIFI-15791
Project: Apache NiFi
Issue Type: Improvement
Reporter: Pierre Villard
Assignee: Pierre Villard
Adds a TTL-based cache for resolved secret values in
ParameterProviderSecretsManager to avoid redundant calls to
ParameterProvider.fetchParameterValues() on every secret lookup. Each secret is
cached independently by its fully qualified name and expires after a
configurable TTL (default 5 minutes). Caching can be disabled by setting the
TTL to 0 sec.
A follow-up improvement will be done to expose an API to invalidate the cache
in case a user wants to force the refresh on the secrets while configuring a
connector.
