Research direction
Start by locating CachedSystemTransactionV2, CachedGraphTransaction, and AbstractBackendStoreProvider, then trace how each ThreadLocal transaction instance registers its StoreEventListener. Check the existing event-hub behavior and related tests, if present. Done means redundant listeners are no longer registered or monitored repeatedly while transaction behavior remains correct.

Before submit
- 我已经确认现有的 Issues 与 FAQ 中没有相同 / 重复问题 (I have confirmed and searched that there are no similar problems in the historical issue and documents)
Environment (环境信息)
- Server Version: 1.5.0 (Apache Release Version)
- Backend: HStore
Expected & Actual behavior (期望与实际表现)
StoreEventListener in CachedSystemTransactionV2 and CachedGraphTransaction will be registered and monitored repeatedly;
Because CachedSystemTransactionV2 and CachedGraphTransaction are both ThreadLocal types in TinkerPopTransaction, each thread holds a corresponding instance. When initializing each instance, it registers a storeEventListener with the storeEventHub held by AbstractBackendStoreProvider. Since each listener implements the same functionality, storeEventHub holds a large number of redundant storeEventListeners
