In Neo4j is the default isolation level always READ_COMMITTED or is it the case only when extending it with Java?

Question

I am reading the documentation provided by Neo4j https://neo4j.com/docs/java-reference/current/transactions/ , but as the link says, the rules provided in that explanation are valid when talking about the java-extension, what about Neo4j without any extension? I am interested in particular in the default isolation level, what is the default one in the basic case?

Answer 1

在所有情况下，默认的neo4j隔离级别为READ_COMMITTED ，这意味着在A完成之前，读取节点/关系的事务（A）不会阻止另一个事务（B）写入该节点/关系。
