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 #10819Add "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 byn 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 memreccommand, 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
