Reuben Kuhnert updated HIVE-13478:
----------------------------------
Description:
Minor cleanup. {{HookUtils.getHooks}} is called multiple times for every
statement executed performing nearly identical work. Cache the results of the
work to improve performance (LRU).
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).
