[英]Cypher query execution time with Neo4j java driver
我正在尝试使用 java 驱动程序找出我的 Cypher 查询的执行时间。
Session session = driver.session();
session.run( "CREATE (a:Person {name:'Arthur', title:'King'})" );
StatementResult result = session.run( "Profile MATCH (a:Person) WHERE a.name = 'Arthur' RETURN a.name AS name, a.title AS title" );
但是我在StatementResult或ResultSummary中的任何地方都找不到它,它由StatementResult.consume(query)
返回。
我可以从ResultSummary
ProfiledPlan
访问数据库命中,但没有关于时间的信息。
有什么办法可以使用neo4j java驱动程序访问Cypher查询执行时间吗?
由于 Neo4j Java 驱动程序版本 1.1.0 有:
/**
* The time it took the server to make the result available for consumption.
*
* @param unit The unit of the duration.
* @return The time it took for the server to have the result available in the provided time unit.
*/
long resultAvailableAfter( TimeUnit unit );
/**
* The time it took the server to consume the result.
*
* @param unit The unit of the duration.
* @return The time it took for the server to consume the result in the provided time unit.
*/
long resultConsumedAfter( TimeUnit unit );
它为您提供了两种时间:
方法位于org.neo4j.driver.v1.summary.ResultSummary
接口上。
