Projeto Descrição

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

Uma nova função de eval () para executar expressões, novas funções de if() e IFNULL (), suporte para configuração de servidor de funções, novos comandos DELETE VERTEX e EDGE excluir, execução de funções de banco de dados de comandos SQL e um novo comando de cluster de criar. Dois algoritmos do gráfico foram empacotados: Dijkstra e ShortestPath entre os vértices. Tempo de abertura quando uma conexão é reutilizada da piscina foi melhorado. Gerenciamento de índices em ordem por foi melhorado. A esquema possui uma nova API para a manipulação de campos personalizados. HTTP/resto tem suporte para busca-plano e limite no "comando".
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".
