OrientDB基于Java的文档数据库
OrientDB是兼具文挡数据库的灵活性和图形数据库管理链接能力的可深层次扩展的文档-图形数据库管理系统(NoSQL数据库)。可选无模式、全模式或混合模式下。支持许多高级特性,诸如ACID事务、快速索引,原生和SQL查询功能。可以JSON格式导入、导出文档。若不执行昂贵的JOIN操作的话,如同关系数据库可在几毫秒内可检索数以百记的链接文档图。
OrientDB v2.2.23 发布了。更新内容如下:
Core
Attempting to remove a non existing field from a class instead of throwing an OSchemaException exception like in 2.1 was dumping an entire stack trace to the logger as an ERROR. As a result in certain conditions logs were filled with unnecessary stack traces, and an ERROR event instead of a WARNING was produced. Now fixed - Internal Issue #8841
A NPE was fixed - Internal Issue #8835
A NPE during database upgrade was fixed - Issue #7512
Under rare conditions, when -1 was being sent as record version, uniqueness constraint was violated and duplicates in the database could occur. Now fixed - Issue #7518
