Currently it calls `this.verticesInTxSize() > 0` which may iterate through all transaction maps. For single-ID queries, you could check more efficiently: ```java // More efficient check for single ID boolean hasLocalChanges = this.removedVertices.containsKey(id) || this.addedVertices.containsKey(id) || this.updatedVertices.containsKey(id); ``` This would be O(1) instead of potentially O(n) for the transaction size calculation. -- This is an automated message from the Apache Git Service.
