Neo4j 3.4.0-alpha07 已发布,Neo4j 是世界领先的高性能图数据库,具备成熟和健壮的数据库的所有特性,如友好的查询语言和事务的 ACID 原则。

Kernel

  • Much reduced memory usage of collision values in importer #10723

  • Rename setting dbms.logs.timezone to dbms.db.timezone #10782

  • Make dbms.tx_log.rotation.* settings dynamic #10819

  • Add "Page cache usage" metric #10861

Cypher

  • Fixes bug where optional match or pattern comprehension with relationship created earlier in the same query did produce too few results. #10842

  • Bugfix so that the cost planner can now plan the following: #10863

    REMOVE CASE WHEN ... THEN a ELSE b END.prop

  • Queries such as match (n),(m) return m as m2, n as m order by m #10867

    were rewritten incorrectly to sort by the wrong column m as m2. Now, the result is correctly ordered by n as m.

  • Fixes planner bug with join hints on optional matches. #10895

Security

  • Remove deprecation annotation for legacy ssl settings #10762

Tools

  • Added a neo4j-admin memrec command, which can print recommendations for the Neo4j heap and pagecache memory settings. #10821

Misc

  • Fix a bug where Causal Cluster store-copy or online backup would occasionally get stuck in an infinite loop during recovery of the temporary store. Also makes store copy faster in HA, CC and online backup. #10843

  • remove initial heapsize settings for neo4j scripts #10851
