项目描述

OrientDB is a NoSQL DBMS which can store 150,000 documents per second on common hardware. Even with a document-based database, the relationships are managed as in graph databases, with direct connections among records. You can traverse entire or parts of trees and graphs of records in a few milliseconds. It supports schema-less, schema-full, and schema-mixed modes, has a strong security profiling system based on users and roles, and supports SQL between the query languages. Thanks to the SQL layer, it's straightforward to use for people skilled in the relational world.

1.3

一个新的 eval() 函数用于执行表达式、 新用和 ifnull() 功能、 支持的功能、 新的删除顶点和删除边缘命令、 执行数据库函数从 SQL 命令，服务器端配置一个新的创建群集命令。被捆绑在两个图形算法： Dijkstra 和 ShortestPath 之间的顶点。开放时间从池中重复使用连接时会得到改善。改进了管理在 ORDER BY 中的索引。架构中有一个新的 API 用于处理自定义字段。HTTP 和休息"命令"中已对回迁计划和限制的支持。
A new eval() function for executing expressions, new if() and ifnull() functions, support for server-side configuration for functions, new DELETE VERTEX and DELETE EDGE commands, execution of database functions from SQL commands, and a new create cluster command. Two graph algorithms were bundled: Dijkstra and ShortestPath between vertices. Opening time when a connection is reused from the pool was improved. Management of indexes in ORDER BY was improved. The schema has a new API for handling custom fields. HTTP/REST has support for fetch-plan and limit in "command".
