认识达内从这里开始

Neo4j 3.3.8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。

更新内容如下：

Kernel

Remove cursor pooling on a page cache level.

Upgrade the Bouncy Castle dependency to version 1.60.

Consistency-checker PropertyReader detects circular property chains

Fixes an issue in IndexHits#getSingle() where it would miss an item when called after a previous call to IndexHits#hasNext().

Remove property key tokens limit from BatchInserterImpl.

Cypher

Fix $12011 by providing the wanted functionality under a feature toggle.

Remove browser warnings when using temporal and spatial property accessors e.g. .year , .x .

Fix 12029 where combining multiple a IN with AND and OR could lead to the wrong result.

Ensure renamed timezones are always returned the same way.

Will now return the same object with timezone set to Canada/Saskatchewan , which Canada/East-Saskatchewan has been renamed to. Previously only the value read from store would be Canada/Saskatchewan

Fix bug in queries containing RETURN or WITH clauses including both a star and a pattern comprehesion (e.g. ... RETURN *, [ (a)-[:HAS_BUREAU]->(bureau:Bureau) | bureau.CREDIT_ACTIVE = "Active"] AS bureauStatus ), which would previously fail with WITH/RETURN should note its Scope in the SemanticState .

Fix bug which would cause FunctionInvocation(...) has to type from semantic analysis errors for some complex WITH -clauses in a write query.

Fix planner regression in which HashJoin + AllNodeScan was preferred

over OptionalExpand in certain cases.

Security

Properly handle multiple authorization providers. Fixes an issue where if one provider failed (e.g. connection to ldap failed) the user would end up un-authorized even though another provider had succeeded.

Causal Clustering

Check recovery status of store when bootstrapping cluster
