Neo4j 面试题与答案
问题 41. What is an index in Neo4j?
An index in Neo4j is a data structure that allows for faster retrieval of nodes based on certain properties. It helps optimize queries by enabling quick lookup of nodes with specific property values.
问题 42. Explain the difference between a property graph and a triple-store graph.
In a property graph, nodes and relationships can have properties, while in a triple-store graph, the graph is composed of subject-predicate-object triples without attached properties.
问题 43. What is the significance of a traversal in Neo4j?
Traversal in Neo4j refers to the process of navigating the graph by following relationships. It is essential for discovering patterns and finding relevant data in the graph.
问题 44. How does Neo4j ensure data consistency in a distributed environment?
Neo4j uses the Raft consensus algorithm to achieve distributed consensus and ensure data consistency in a distributed environment.
