Zhihua Deng updated HIVE-29645:
-------------------------------
Description: This refactoring aligns with the long-standing objective of
mitigating the size and complexity of the ObjectStore
implementation(cf.HIVE-14730). By decomposing the large RawStore/ObjectStore
into smaller, domain-oriented store interfaces and implementations, we can
reduce the complexity and maintenance of ObjectStore, improve separation of
concerns,andcreateacleanerfoundationforfutureevolutionofmetastorepersistencelogic.Italsocentralizestransaction/querylifecyclemanagementthroughhelper/proxyabstractionssothatthenewsub-storescanreusetheexistingpersistencebehaviorwithoutduplicatingboilerplate
