-------------------------------------
Summary: [Cleanup] Improve HookUtils performance
Key: HIVE-13478
URL: https://issues.apache.org/jira/browse/HIVE-13478
Project: Hive
Issue Type: Improvement
Reporter: Reuben Kuhnert
Assignee: Reuben Kuhnert
Priority: Minor
Minor cleanup. {{HookUtils.getHooks}} multiple times for every statement
executed performing nearly identical work. Cache the results of the work to
improve performance.
Also introduce the {{@CacheableHook}} annotation which can be appended to hooks
that don't need to be re-instantiated using expensive reflection (such as
Sentry hooks that load configuration on initialization).
