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.
RETURN datetime("2018-04-05T12:34:00[Canada/East-Saskatchewan]") MATCH (n) WHERE n.date = datetime("2018-04-05T12:34:00[Canada/East-Saskatchewan]") RETURN n.date
Will now return the same object with timezone set to
Canada/Saskatchewan
, whichCanada/East-Saskatchewan
has been renamed to. Previously only the value read from store would beCanada/Saskatchewan
Fix bug in queries containing
RETURN
orWITH
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 withWITH/RETURN should note its Scope in the SemanticState
.Fix bug which would cause
FunctionInvocation(...) has to type from semantic analysis
errors for some complexWITH
-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
Tools
Revert mistakenly enabling NEO4J_DEBUG by default for neo4j-admin
Browser
Add
:history clear
commandAdd pagecache hits and misses to plan output
Add complete support for bolt+routing://
Add Neo4j Community Forum link to sidebar
Enable users with non reader roles to connect
Fix
:server switch
bug in Neo4j Desktop environmentFix username not updating in sidebar when disconnecting
Improve Cypher result rendering performance
Prepare for Neo4j Desktop distribution
Fix issue where editor buttons would overflow the viewport
Fetch fresh version of remote guides on every request
